Updated: 10 best Android launchers: amazing ways to supercharge your phone

Updated: 10 best Android launchers: amazing ways to supercharge your phone

Best Android launchers


Nokia Z launcher


Spend more than three minutes with any Android fanboy, and you'll quickly learn that the real beauty of Google's operating system lies in the potential to customise it.


Any problem can be solved by downloading enough apps. Nowhere is that more true than for Android's homescreen – so we've rounded up the best alternative Android launchers for your modding pleasure.


On an Android phone, the launcher is the app responsible for the home screen, the app 'grid', and launching the aforementioned apps. Phones generally come with either the stock Google launcher, or more commonly, a launcher whacked on top by a hardware manufacturer like Samsung.


But, if you don't get on with your phone's default launcher, installing a new one just takes a quick visit to the Google Play Store.


1. Nova Launcher


Nova Launcher


Nova and Apex (below) are the two standout Android launchers – both strike an excellent balance between having enough features to customise things, without bogging you down with unfeasibly long options lists and 17 levels of sub-menu hell.


Nova's arguably the better of the two, with a few more options available in the free version (there is also a Prime version), and slightly better performance – but really, we're splitting tiny Android hairs trying to find a difference between the two.


2. Google Now Launcher


Google Now Launcher


Google's very own stock Android launcher strips thing down to the basics, but just because it's the Android standard, doesn't mean it's boring. For your money (well, actually, it's free), you get easy access to Google Now, button-free voice controls, and enough transparent window-bars to make you think you're back in Windows Vista.


It's compatible straight out of the box with all Nexus and Google Play Edition devices, and two minutes with a computer will get it running on all Android 4.x handsets. Just be careful what you say around it – the Big G's always listening, probably.


3. Yahoo Aviate Launcher


Aviate


Yahoo snapped up Aviate in the early stages of its development, and it's turned into one of the best contextually-aware launchers available. Aviate collects apps together based on different activities, and will then suggest items that you're likely to use.


By telling Aviate your home and work location it'll know which apps to offer when you're in those locations. Heading to the office? The moment you leave the house, Aviate will offer navigation apps and anything else you regularly use on your journey, such as Spotify. Another example: at night, Aviate will give you shortcuts to set an alarm, see the next day's weather forecast, or put your phone into 'do not disturb' mode. It's not the most customisable launcher out there, but Aviate is a smart, simple and effective personal assistant.


4. Nokia Z Launcher


Nokia Z


Nokia's own Z Launcher is another one that helps you get to your most used-apps and sites more quickly. By learning your habits and taking into account your location and the time of day, the Z Launcher will surface what it believes to be the most appropriate items. Plus, the more you use it, the better it gets, as the app learns more about your habits over time.


Another neat trick lets you get to an app faster by simply drawing the first letter of its name in order to produce a narrow list of results. And the more often you use a certain app, the Z Launcher will remember. It also has a pleasingly simple, unobtrusive interface, with apps arranged in a neat line.


5. Buzz Launcher


Buzz Launcher


Buzz Launcher packs the standard set of customisation options, but with a killer advantage: a user-created library of thousands of themes and widgets you can browse, download and tinker with. Whereas other launchers feel like masterpieces of efficiency – trying to find you the app you want, with minimum hassle – Buzz is all about the aesthetics.


There are certainly more powerful launchers out there, but if you're all about matching the colour of your shoelaces to your cravat (and don't have an iPhone), then this is probably the launcher for you.


6. Apex


Apex Launcher


Apex Launcher, just like Nova, blends smooth performance and ease-of-use with a good level of customisation to create a genuinely appealing alternative to most standard Android launchers.


Standout features on Apex include a superb tablet mode (finally allowing Nexus 7 owners to rotate the home screen); and the Pro version has the fantastic Apex Notifier service, which pushes notifications to a widget on your home screen. (Although, Notifier requires running an extra app in the background, which is a small drain on battery life.) Once again, the Pro version does cost money, so it's worth downloading the free version first.


7. Action Launcher Pro


Action Launcher


Action Launcher has some nifty, unique features – stuff like a quick-access set of shortcuts (all customisable, of course), special gestures for launching apps from within folders, and a cool one-touch method of creating widgets from apps.


Sadly, you have to pay the requisite couple of quid for the premium version if you want to get your hands on the goodies.


8. ADW Launcher


ADW Launcher


ADW's probably the ultimate modder's launcher – anything you want to tweak is tweakable, from the particular shade of Gmail red, to the precise gesture needed to open an app.


Sadly, it all comes at a price – ADW is complicated to use and sluggish compared to other offerings. More worryingly, development has ground to a halt, with no new releases to support versions of Android after 4.1.


9. Next Launcher


Next Launcher


Some will consider Next Launcher jaw-droppingly cool – a 3D launcher that's completely different to the standard grid-with-some-widgets-whacked-on-top. Of course, it's insanely impractical and a complete battery hog, but it might just impress a girl at the bar on Friday night.


However, it costs more than a Blu-ray, which is money that could be better spent buying drinks at the aforementioned bar instead.


10. Zeam


Zeam


Zeam is at the other end of the spectrum to the rest of these launchers – all the developers seem to care about is speed. It's the stripped-out racing version, ditching pretty much all the customisation options or swanky floating menus of the other versions, in favour of a minimalist code-base.


The upside of course is super-smooth performance, even on the oldest, crummiest phones around. If you're looking for a speed boost for a handset running Gingerbread (that's Android 2.x to you and us), Zeam fits the bill pretty well, and it's also free.

The best drones to fly in 2015

The best drones to fly in 2015

DJI Inspire 1 H500


DJI Inspire 1


DJI Inspire 1


Not content with having cornered the consumer drone market – and every news bulletin – with its amazing Phantom 2 Vision+, DJI has now launched a stunning mid-range drone aimed at prosumers. Like the Phantom, the new Inspire 1 is ready to fly straight out of the box using an iPad or Android tablet to monitor the action. The high-tech hand controller is a joy and equipped with ultra smooth joysticks and extra switches for controlling the quad's retractable carbon fibre prop arms and its new 360˚ 3-axis, modular gimbal. Naturally, it all comes pre-configured with DJI's trusted GPS technology and all the usual fail-safe modes, including auto take off and landing. It can even fly steadily indoors without GPS using its clever Optical Flow positioning sensor.


The Inspire 1's own-brand camera is equipped with a Sony 1/2.3-inch CMOS sensor and shoots 4K at 30fps and 1080p at up to 60fps with no GoPro-style fisheye to taint the view. It also takes excellent 12MP stills in JPEG or RAW. What's more, the camera and gimbal can also be operated by a second person using another hand controller; just like the pros do it. Expect around 20 minutes of flying time from the drone's intelligent 5700mAh 6S battery.


In the pantheon of camera-wielding UAVs, the Inspire 1 is an unequivocal winner. Think of it as the Audi R8 of drones: its gentle controls are perfectly dialled for smooth, rock steady videography but slam the stick forward and it shoots off at speeds in excess of 45 mph, twisting and turning like a dragonfly on steroids. Right now, this thing is matchless.


From £2,380, dji.com


Walkera Tail


Walkera Tali


Walkera Tali H500


The Tali H500 has six blades instead of four so there's every chance you'll land it in one piece should a motor give up the ghost. It's also several inches bigger and more powerful than DJI's Phantom, and it comes with retractable landing gear so the camera's view isn't obscured by the legs.


The Tali H500 is superbly built. This isn't some shed-made Heath Robinson affair – it's a bona fide, factory-produced UAV equipped with a reliable set of pilot-aid components like GPS, return to home, even a fly around setting for circular flights. The 5400MAh battery delivers around 18 minutes of safe flying time. Like DJI's Inspire 1 and Phantom 2 Vision+, the Tali H500 comes out of the box ready to fly and is equipped with a 3-axis gimbal and Walkera's own iLook+ GoPro-style camera. Unfortunately, the camera might be the package's weakest link. It's no match for the GoPro or the Phantom camera, but it works seamlessly with the rest of the system, allowing pilots to control the camera and gimbal from the ground while viewing what the camera sees on the transmitter's small but decent colour monitor. Thankfully, the gimbal cage is just the right size to retro fit a GoPro, though you will need to spend an extra £100 or so on some video uplink components if you plan to fit one.


The Walkera's Devo 10 remote is one of its strongest facets. Aside from two gimbal controls, there are switches aplenty: one for retracting the landing gear, another for auto take off, another for GPS and manual modes and yet another for setting the circular flying mode. The flip-up colour monitor isn't iPad Mini standard but it's good enough for composing shots and seeing where you're going. If you're looking for a UAV that flies exceedingly well and doesn't look like a toy, then this is the one to go for. However, we advise you swap the iLook+ camera for a GoPro.


£1,220, hobbyone.com


Parrot BeBop Drone


Parrot Bebop


Parrot Bebop Drone


When Parrot launched its camera-equipped AR Drone back in 2010, it inadvertently kick-started a whole new category of consumer electronics. Well here's another Parrot to add to the flight list. The lightweight, four-motor Parrot Bebop Drone is ready to soar out of the box and comes rammed to the hilt with an ample shedload of electronic wizardry that makes it both chimp-easy to control and extraordinarily stable in flight, especially when flown indoors.


Most current drones use a range of sensors and a GPS receiver to help keep them steady in flight, but this one appears to have the Full Monty, including an accelerometer, gyroscope, magnetometer and ultrasound. The HD camera-equipped Bebop is available in two packages. The basic kit is comprised of the drone and a pair of small LiPo batteries and you fly it using an Android or iOS tablet. The Bebop's free app provides full control of the drone by simply tilting the tablet screen in the direction you want it to fly. The app also includes camera controls, in-flight stats and a button for automatic take-offs and landings. The posher package adds another £340 to your spend but for that you get a damn decent hand remote which increases the Bebop's flight distance from a bogstandard 300 metres to around two kilometres. It's called the Skycontroller and we highly recommend it.


The Bebop eschews a camera-steadying gimbal in favour of a fixed fisheye lens and a cluster of complex algorithms that cleverly keep the image stable and allow the user to tilt the view up or down without the camera actually moving. The result is pretty steady video imagery with no barrel-like horizon distortion like that on the GoPro. However, it's a far from perfect solution as you can only tilt the camera down a certain degree; a proper motorised gimbal can usually tilt a full 90˚. Image quality, too, is nowhere near as good as that of the GoPro or DJI's Phantom 2 Vision+. Nevertheless, if you're new to drones, not too discerning about video or picture quality and don't have enough cash for a Phantom, then by all means give this tough, well-built bird a whirl.


From £430, parrot.com/uk


Hubsan X4


Hubsan X4


Hubsan X4


The palm-sized, ready-to-fly X4 is perfect for indoor flight, though it is very sensitive to control input which makes it quite tricky to fly, even with a 6-axis flight control system on board. Due to its diminutive size (just 70mm x 70mm) and consequent low weight, the X4 should only be flown outdoors in a light breeze. Anything stronger and the little fella may struggle to hold its position and may possibly even be taken with the wind. While this drone's fixed 0.3 megapixel camera can't compete with the Phantoms of this world, it's more than capable enough for casual consumer use. The camera shoots in 720p or 480p and recordings are saved to a microSD card on board the craft. However, as there is no screen to monitor what you're shooting, video and image results can be a bit hit and miss.


£80, red5.co.uk


DJI Phantom 2 Vision Plus


Phantom 2 Vision+


DJI Phantom 2 Vision+


Although it's been out the best part of a year, the ubiquitous Phantom 2 Vision+ is still one of the most stylishly presented RC flying camera packages on the market. It's superbly built and needs none of that Meccano-like construct-it-yourself malarkey required of some other brands. In fact, it's ready to fly straight out of the box. Simply spin the four props onto their respective spindles, bung four AA batteries into the transmitter, charge up the Phantom's snap-in Li-Ion battery, clip your iPhone to the transmitter and you're ready to go.


The Phantom 2 Vision+ comes equipped with a specially designed 14 megapixel GoPro-style camera mounted below the drone and integrated with a 3-axis gimbal that ensures smooth, rock steady video footage. The camera also transmits its field of view back to the iPhone, effectively turning the drone into a bona fide FPV (First Person View) aircraft. This bird is still the most popular drone on the market and justifiably so. It flies remarkably smoothly, is reliable in flight and is reasonably priced for a flying camera capable of nabbing video and stills from such amazing aerial perspectives.


£940, dji.com


Steadidrone Flare


Steadidrone Flare


Steadidrone Flare


The lesser-known, South African-produced Steadidrone Flare costs nearly £1,000 more than the DJI Phantom 2 Vision+ but around £450 less than the DJI Inspire 1. However, it isn't anything like as integrated a package as the DJI models; for instance, you will still need to buy a monitor to view what the camera sees for FPV flying and aerial videography. Nevertheless, the Flare does have a few tantalising features up its sleeve. Firstly, it isn't camera specific so it can carry a variety of small cameras like the Sony RX100 and, of course, any model of GoPro.


Given that a delicate camera gimbal is usually the first thing to be destroyed in a crash, we like the fact that the camera on this drone is mounted up front, away from most of harm's way (unless, of course you fly straight into a building). You can also mount a GoPro in its protective underwater housing which adds extra peace of mind. But perhaps best of all is that the whole drone can be easily folded into a very tidy and portable package; a boon for anyone hiking out to suitably cinematic flying areas. The Flare is constructed almost entirely from carbon fibre and features the usual gamut of in-flight safety features – including the now obligatory GPS for steady, user-friendly flying.


€2425, steadidrone.com


Sky Hero Little Spy


Sky Hero


Sky Hero Little Spy


This UAV manufacturer has adopted a modular design system which is fantastic for avid modellers and those with a keen knowledge of UAV terminology but not so good for the casual consumer who just wants to fly straight out of the box. Nevertheless, being able to mix and match components can be considered a big bonus for those serious about their hobby. There are four main base models in the Spy Hero range – Spy, Spyder, Spyder 6 and Little Spyder – and each one can be upgraded at will. For instance, you might start with a basic Spy model and decide later on that you'd like it to have a bigger footprint and perhaps have it take a heavier payload. No problem, just order some longer carbon fibre arms, more powerful motors and a few extra components. Sky Hero is a highly respected manufacturer of top-quality UAVs, but it will need to start offering ready-to-fly models en masse if it really wants to compete with the likes of DJI, Walkera and Parrot.


From £325, droneshack.co.uk


Hubsan Q4


Hubsan Q4


Hubsan Q4


This nano quadcopter measures just 5cm x 5cm, which is roughly the size of a matchbox. It doesn't have a camera on board (that would be asking a little too much) but it flies exceptionally well given its tiny proportions. In fact, you can literally throw it in the air and, assuming you have some power on the stick, it'll level off and hover. True, the small hand controller requires extremely subtle input – a millimetre too much on the throttle stick and it's sure to clout the ceiling – but it's a great way to hone one's flying skills in preparation for something bigger. And, at just £30 a pop, it'll be no major loss if it ends up inside the dog.

How Microsoft's Clutter can tame your email inbox and save you time

How Microsoft's Clutter can tame your email inbox and save you time

Introduction


Keeping spam out of your inbox isn't easy – around 99% of all the email messages sent are spam and even if only a few get through, they're annoying and can be dangerous. Those iTunes receipts and PayPal account warnings you weren't expecting are often trying to slip malware onto your system.


But legitimate email you don't actually need to read is also a huge drag on productivity. Whether it's newsletters you didn't sign up for (often known as bacon, because they're tastier than spam) or the endless discussion about where to have the team lunch this week, irrelevant email is why so many employees would rather use social media or messaging services.


Cutting through the Clutter


To stop people abandoning email in frustration, Microsoft launched a new feature called Clutter as part of its Office 365 cloud service, and this files away messages it thinks you don't need to read using machine learning to simulate your world – and what you care about.


"We're trying to address the biggest pain point in email, which is information overload," John Winn of Microsoft Research in Cambridge told us. "This causes the most pain, because when you have so many emails coming in to your inbox it's difficult to focus on the high priority email – the ones that you need to take action on."


The problem is that what's interesting to you might be clutter for me, unlike spam.


"What's spam for you is spam for me," Winn points out. "Clutter is a very personalised model; it's about learning which emails are low priority and which are high priority for you, because the same message can be high priority for one person and low priority for another person."


"We learn from the signals you provide just by working normally; what messages do you read, what do you reply to, which do you forward? Which are likely to be of interest, actionable or high priority? And messages that aren't any of those can be removed and placed in a 'next door' inbox you can look at any time you want."


Seamless system


It doesn't need a special client the way Gmail's Inbox does, because it just happens in Exchange – and you can look at your normal email and your Clutter-filed mail in any mail client, because it's just a normal folder.


Clutter gets information from the Office graph as well as from the email message itself. It looks at who sent the message, whether it's sent just to you, or if you're only on the CC list, as well as examining the words in the body and subject, and the Office graph tells it how you treated the email – whether you replied to the message or forwarded it, whether you deleted it or moved it to another folder or marked it as unread, and how long you spent reading it.


"We match those signals from the email and your behaviour and we take a fresh email and say, 'what is the likely behaviour? Will you read it urgently or ignore it?'" explained Winn.


Cleverly, Clutter takes into account that you don't always treat email the way you mean to. For a start, it waits up to a week before saying you've ignored a message (because you might just be busier than usual), but if you take an action like replying or deleting, it can take that into account straight away. If you're on holiday and you're treating email differently – not replying to messages that would otherwise be urgent – it models that as well.


Bring the (label) noise


There's also a concept called 'label noise'. This pertains to "when your actual behaviour differs from your ideal behaviour – when the action that you should take or maybe the action you intended to take isn't what you do," Winn explained. "You intend to reply but you don't; or you reply to another message from the same person instead, because it's the most recent mail from them. We explicitly model those behaviours."


The idea is to make Clutter accurate and sensitive to the subtle nuances of the way we handle email – and to do that without a mass of complicated machine learning code for all these special cases that would make it hard to maintain.


It works by using all the information from Exchange and the Office graph to build a probabilistic prediction model that simulates what you'll do when you get a new email. Unlike older systems that keep the whole model in memory – which slows things down – Clutter uses Microsoft's Infer.NET compiler. It runs fast enough to handle the petabytes of information in Exchange, and adding the idea of 'label noise' to explain unexpected user behaviour takes only a few lines of code.


This also made it easier for the MSR team to work with the Exchange group. "In the early days we would talk the Exchange team through our program and what assumptions we were making and they could easily see what we were doing. And they'd say 'that's not right! We know users do this in Outlook, not that' and we could quickly go back and modify our model of what a user does," Winn told us.


No interference


This approach is one of the reasons that Clutter became a feature when other ideas the researchers had come up with in their four years of working with the Exchange team didn't get anywhere. "We've been exploring a number of different ways that machine learning could work in the inbox," Winn said. "Only with Clutter did we feel we'd got something that can really add value, and not be in some way creepy or have the negativity you can sometimes get when you start applying machine learning to personal email."


We may all complain about email, but people quickly get unhappy if their mail system 'interferes' with their messages – and gets it wrong. So far Clutter is well received – and Winn hopes to extend it beyond email.


"The opportunity is very broad. We're looking at other applications in Microsoft products. Some I can't talk about, but there are some already in the Azure ML service and we're actively working with both Exchange on future work with Clutter and with other product teams on using probabilistic predictions in other products."


One possibility is working not just with the structured information in the email header but also the unstructured information in the message itself. Winn calls unstructured text "the last uncomputable data – it isn't easy to compute with, so it tends to just sit there."


The latest version of Infer.NET is better at working with unstructured text, like the content of email or Office documents. That means in the future, Clutter might be able to understand what a mail message or attachment is about, to decide if you'll be interested in it – and that would be much more accurate.
