Money doesn't grow on trees, and those $0.99 app purchases do add up. It's best to go into the Play Store with some idea of what's up your alley and what isn't. That's what the Google Play App Roundup is here to do. We bring you the best new and newly updated app and games every week. Just click on the app name to head to the Play Store and test it out yourself.
Your phone came with the Gmail app, and maybe you've since branched out to the Inbox app. Support for non-Google email accounts in Inbox is poor, but the new Email app from EasilyDo is a bit like Inbox for whatever email account you want to use. It's essentially an email app wrapped around the EasilyDo Assistant app.
Adding an account is very quick, especially for Gmail accounts you already have on your phone. Just select it and you're done. There's also a guided setup process for popular apps like Yahoo, Outlook, and AOL Mail. You can also plug in any other account via IMAP. Syncing and general app navigation are quite fast.
Your inbox defaults to a Gmail-style conversation view—the app doesn't try to imitate Inbox's bundling. The style is a little different, though. Instead of seeing all the emails collapsed in one screen, tapping on an email brings up a new screen with a list of all threaded messages. I don't know if I like it more than Gmail's approach, but it's something new.
One of my favorite things about EasilyDo Email is the customizable swipe gestures. Each message in the inbox can be swiped left or right. You can have those gestures do things like archive, delete, and mark read/unread. The assistant functionality is neat as well. You'll find this in the navigation panel. The app automatically finds emails that fit into categories like travel, subscriptions, and packages. Tap on any of them to get a filtered view of your inbox. Some of these lists will include a handy breakdown of all the relevant details. For example, flights found in the travel list have flight numbers, reservations, seat numbers, and times. The assistant seems reasonably smart, but it does miss some things.
The subscriptions section also showcases one of Email's main features; one-tap unsubscribing. You'll see this button at the top of any email it detects as a subscription with a supported method of removing yourself from the list. It seems to work on most of my email subscriptions. Simply tap the button, the app thinks, and you're unsubscribed.
EasilyDo Email is free, so check it out if you want to get a different take on your email.
I've talked about RC rock crawlers before, and I've also taken a look at small-scale indoor cars. This time around, I'll combine the two and also toss in a dash of FPV. Rock crawlers are especially good for indoor driving because you do not need a lot of space, nor do you have to worry about having a smooth, spotless floor. In fact, as driving surfaces go, the rougher, the better.
The vehicle I chose is the Temper ($80), a ready-to-run model from ECX. This model is available in either 1/24 or 1/18 scale. I chose the 1/24-scale version, which is the same scale as most plastic car models. It is about 6.75" (171mm) long and 4" (102mm) wide.
In many respects, this downsized crawler is just like my larger 1/10-scale machine (which is a lot like full-scale crawlers). It has full-time 4-wheel-drive, locked differentials, 4-link suspension, super-soft tires…all the stuff you would expect on a rock crawler. The only obvious difference is that the Temper uses friction dampers rather than oil-filled shocks.
A 2.4GHz radio system is included. The transmitter looks smaller than most others, but it is a comfortable fit in my hand. It has servo reversing and adjustable control rates. It's a neat, compact piece. The receiver and ESC are combined into one unit aboard the car. Steering is handled by a tiny analog servo.
Power comes from a 4-cell 150mAh NiMH battery. The battery is removable, so you can buy a few spares ($14) and not have to worry about down time. The included charger is a simple USB-powered device. To be honest, I haven't had much luck with it. I've tried powering the charger from a few different USB sources and it never seems to give the battery a full charge. I've reverted to using my Hitec X4-Eighty charger (huge overkill) with good success.
The Apollo 11 Moon landing in the summer of 1969 captured the world's attention and had everyone looking skyward. But while Michael, Neil, and Buzz were swiftly heading away from the surface of the Earth, NASA was also involved with another unprecedented voyage travelling in the opposite direction. Only no one was watching.
A small research submarine, called the Ben Franklin, carried a crew of highly-skilled explorers to locations never before visited by humans. Much like the astronauts headed to the lunar surface, the submariners placed themselves in great danger to expand our scientific knowledge and scratch that uniquely human itch to explore the unknown.
NASA oceanographer, Dr. Gene Carl Feldman, sums up the parallel efforts:
"I grew up in the 60s, a decade of exploration. We were going to the moon and we were going to explore and colonize the sea. The sea was the next frontier just as space was the next frontier.
There were two culminating expeditions: one to the Moon, one to the Gulf Stream. These missions were the ultimate voyages of exploration for their respective disciplines. There was no space mission greater than Apollo 11. And there was no expedition to the undersea world greater than the Ben Franklin. What was amazing was that both of these missions took place at the end of July in 1969."
The Gulf Stream Drift Mission was an endeavor with many widely-varying scientific goals. Its core objective was to map and study the Gulf Stream, the Atlantic Ocean's northward-flowing current of warm water that stretches from the Gulf of Mexico to Europe and Africa. The effects of the Gulf Stream are wide reaching. It had often been the subject of previous scientific study, including pioneering work by Benjamin Franklin. What made this effort particularly unique is that the 6-man crew and the myriad instrumentation were not housed on a surface ship. Rather, they remained cocooned in a submersible vessel for the entire 30-day voyage covering more than 1400 miles (2250km).

If you're going to be supporting app development on Android (and you should), you might as well pay for the best content you can. That's what the Google Play App Roundup is all about. This is where you can come every week to find out what's new and cool on Android. Just follow the links to the Play Store.
Most of the alternative home screens on Android are generally similar, but every now and then a developer just goes in a different direction. Such is the case with Peek Launcher. It eschews many of the things that other launchers have, relying almost entirely on T9 text input. It's an interesting minimalist take on the home screen.
When you start up Peek Launcher the first time, you'll get a regular phone dial pad at the bottom of the display and two rows of icons. The icons that show up are predictions based on what you've been using most lately. Newly installed apps will also pop up here. To find an app, just start tapping the keys to spell out the name. So for Gmail you'd tap 4, 6, 2, and at that point you'd probably be left with just Gmail. It filters the list of apps live as you tap.
There are other launchers that include features like this, then there are some apps that just do this alone. Peek Launcher is the only one I'm aware of that is based almost entirely on T9 input. In addition to filtering apps, you can long-press the icons to pin important apps so they'll always show up on the main page. There are swipe gestures too. Drag down to get your Google search bar, and drag up to reveal a full scrollable app list.
Peek Launcher includes options to change the background and button color of the keyboard. It will also change automatically when you set a new background to match the colors. You can set a custom icon pack as well.
This app is still early in its development, and it's changing fast. It is a little light on features right now, but it's free. I'll be watching to see what Peek can do down the line.
The 2017 phone season is just starting to spin up. The lineup is almost unchanged right now, but there are a big couple of months right around the corner. We expect flagship phones from Samsung, HTC, and LG to show up, and that means you have to be more picky than ever when buying a phone. You could wait it out and see what these upcoming phones look like, but there are still good choices right now. Let's break it down.
Despite being almost a year old, the Samsung Galaxy S7 is still the best overall choice for a carrier phone. Samsung is in the process of rolling Android 7.0 Nougat out to the GS7, which makes it a bit more appealing. It's not the only choice you have, though. Verizon customers have the Pixel, and there's the LG V20.
Let's start with the Galaxy S7, which is still worth considering. The hardware is still fantastic. I pick up the GS7 Edge sometimes and am still wowed by the curves. The front and back are both Gorilla Glass, but it feels so well put together. The phone is IP68 water resistant, so it can take a quick dip and be fine. It's a little heavier than you probably expect when you pick it up, but the back has a slight curve, making it comfortable to hold.
The Galaxy S7 and S7 Edge have Super AMOLED panels at 2560x1440 resolution. The GS7 is 5.1-inches, while the Edge variant has a larger 5.5-inch display. They are still the best panels you can get (now that the Note 7 is dead). They're bright, have perfect viewing angles, and the colors are very accurate. Then there's the Edge with a screen that curves down on both the left and right sides. It looks cool, but it's actually less comfortable to hold. The Pixel XL's display is almost as good, but it's not as bright and the colors are flatter. Samsung still wins on this front.
Google devised Android in a way that allows device makers to take the lead on modifying the software to support whatever crazy hardware gimmicks they want to try. Sometimes this has led to some interesting innovations, and other times it's been a mess.
Some of the hardware fads over the years look bizarre and even foolish in retrospect, but this is all part of the process. Some fads ended up changing the nature of the Android devices we have today.
Plenty of people use multiple displays on their computers, but on Android devices? This was another famously poor example of mobile hardware gimmickry. A number of Android devices with dwo displays were launched in 2011 and 2012 including the Kyocera Echo, LG Flip II, and the Sony Tablet P.
Even today, Android doesn't really support dual-screens, and it barely even supported large format screens in 2011. That meant all the code managing the secondary displays of these phone and tablets was integrated by the OEM. Therefore, the only apps that could take advantage of the special features enabled by the hardware were the ones built-into the device. Oh, there were APIs for developers to add support, but guess how many did. Yeah, none.
This idea was left behind, at least for the most part. The Russian YotaPhone bumped around a few markets until 2015. This device had an e-paper rear-facing display. It was a little better supported, but the niche wasn't very interesting to consumers in practice. Now, there are a few phones with secondary ticker displays (more on that later).
Getting into the RC hobby has never been easier or more affordable than it is right now. There are tons of high-quality, beginner-oriented RC vehicles to choose from. However, there are also a lot of sub-par products as well. Even with the right equipment, learning the ropes can sometimes be a challenge. Making a few missteps as you're just getting into the hobby can ruin your enthusiasm and sour the fun. Here are a few tips to help potential RC hobbyists make a positive start.
Whether you are interested in aircraft, cars, or boats there is probably someone in your area who is already up to speed and knowledgeable. Seek out RC clubs, racetracks, or hobby shops. You are bound to find folks who are willing to help you get started.
If flying is your goal, attend a club meeting even before you buy any RC equipment. Most RC clubs have dedicated instructors who teach newcomers how to fly. The majority of aspiring pilots who try learning all by themselves either fail completely, or destroy many models on their path to competency. Also, an instructor can help you choose the right equipment. Some clubs even have models set aside just for training.
If you're more interested in surface vehicles (cars, trucks, boats), find out what models experienced hobbyists in your area are using and recommend. It can be a big boost to have local experts who are familiar with your specific equipment. You're bound to receive helpful advice for setup, maintenance, and repairs.
If you live in a rural area, you may have trouble finding other modelers nearby. There are numerous online forums such as RC Groups and RC Universe that can sometimes partially fill that void. Just be wary of advice received online. There are a lot of self-proclaimed experts who give out bogus advice. With a little research, the true experts are often easy to identify.
The bottom line is that RC is as much a social activity as anything else. Finding other modelers with similar interests makes the RC hobby more enjoyable and also speeds up your learning curve.
Autel Robotics is a fairly new player in the world of aerial photography (AP) platforms. They currently offer two multi-rotors in their product line, the X-Star WiFi ($700) and X-Star Premium ($750). Both of these ships have a 350mm plastic airframe, brushless motors, and a 4K-capable camera. Power comes from a 4-cell 4900mAh LiPo battery. The whole thing is factory assembled. You only need to go through a few setup and calibration steps (and read the manual) to prepare for flight.
This review covers the X-Star Premium. You can view a comparison chart for a summary of the differences between the two X-Star models. There are actually more similarities than variances. But there are two features found only on the premium model that make it the better value in my opinion.
The X-Star Premium includes a hard-shell case that is useful for storage and transport of the quad and its accoutrements. The package comes with one battery, but there is room for a spare inside the case. If you use a tablet to view the video feed, that will also fit inside the case. If you've ever tried to individually schlep all of the gear necessary for an AP flight, then you know how much of a benefit a carrying case can be.
The other factor that tips the scale for the premium model is the video downlink system. The X-Star Premium uses a 900MHz system that routes the signal to the quad's radio transmitter (which effectively makes it a transceiver…semantics). This signal then gets to your phone or tablet screen with Autel's Starlink app and a hard-wired USB connection. The X-Star WiFi uses a 2.4GHz WiFi signal directly to your device.
I'll admit that I've never tested the video system on a standard X-Star. I have, however, flown numerous other AP multi-rotors that used WiFi-based video systems. I've had a few good experiences with WiFi video. Some systems, however, suffered from chronic connection problems and they all had some degree of signal latency. As far as I'm concerned, when there is a non-WiFi option, you should take it.
There are far too many apps flowing into the Play Store on a daily basis to find all the good stuff yourself. This is the problem that Google Play App Roundup seeks to solve. Every week we tell you about the best new and newly updated apps in the Play Store. Just click the app name to head right to the Play Store and check things out for yourself.
There are a number of services that offer access to live TV streams on Android, but they tend to want money. BitTorrent Live is a streaming TV service from, you guessed it, BitTorrent. It's completely free. It's been available on some streaming boxes and desktops for several months, but the app has now showed up in the Play Store.
As with most things BitTorrent does, this streaming video app is based on the company's p2p technology. It uses many of the same techniques that have allowed Torrent sites to become so prominent as sources for… well, everything. BitTorrent itself is a legitimate business, though. The content on BitTorrent Live is fully licensed.
Because this is based on p2p technology, the quality of the stream will vary based on how many people are viewing it. Just like with a Torrent download, you both download and upload to keep the swarm of watchers going. The result is a system that's much easier on the video source. How does it look? From my testing, I'd say it ranges from middling to good. Some channels look like a standard 480p stream, and other are almost as good as what you'd get streaming HD video from a source like YouTube.
The interface is minimal, and I think it could use a bit of work. You can tap to bring up the current stream info, then tap the arrow at the bottom to get the full channel list. There are nearly 20 channels, some of which are not going to have wide appeal, like the far, far right One America News network. You do get the NASA TV and NASA UHD stream, though. Scrolling through the horizontal channel guide is not pleasant. Inertial scrolling is ramped way up, and any downward movement is interpreted as a swipe to close the guide.
There are some other bugs here too. For example, the stream fails to load on mobile data, so you need WiFi right now. It also strikes me as odd there's no Chromecast support at launch. Still, the app is free and it does offer free streaming video as advertised.
At this time of year, winter weather forces many of us to scale back outdoor RC activities. But there is still plenty of fun to be had indoors, including multi-rotor FPV racing. Indoor FPV racing is becoming very popular for reasons that go beyond its weather advantages. Compared to outdoor FPV racers, these tiny indoor machines are less expensive and just as durable. It's also easy to set up a racing course right at home with just about anything you have on hand.
The machine responsible for kickstarting the current indoor racing boom is called the Tiny Whoop. It is basically a Blade Inductrix mini quad with more powerful motors, an FPV camera, and video transmitter added on. The first generation of Tiny Whoops were basement-builds by industrious pilots. Now, Blade has released a new version of the Inductrix that includes the hop-ups necessary for indoor FPV racing, the Inductrix FPV.
There are two versions of the Inductrix FPV. The Bind-N-Fly model ($100) includes the souped-up quad and a 200mAh LiPo flight battery. This is usually the preferred model for pilots who already own a Spektrum radio and FPV goggles. The Ready-to-Fly model ($200) adds a small transmitter as well as a 4.3" (109mm) video monitor. This package is for pilots who are starting from scratch. Horizon Hobby provided a Ready-to-Fly set for this review.
The Inductrix FPV is a small quad. It measures 64mm between diagonal motor shafts. Once you factor in the propeller shrouds, the diagonal dimension is just over 100mm. Those shrouds are very important aspects of the Inductrix's suitability for indoor FPV. Not only do they protect the props and whatever you crash into, the shrouds also act like cushions to soften the blow. I can't tell you how many times I've flown into something, only to have the quad bounce back in the other direction while still flying. It is probably the most crash-resistant indoor quad I've ever flown.
The onboard FPV gear consists of a tiny camera with an integrated 25-milliwatt 5.8GHz video transmitter (VTX). An amateur radio license is required to legally operate this VTX in the US. This system can broadcast on 16 different channels, including the new Raceband frequencies. These components are housed within a protective plastic shell that screws to the quad frame.
Your phone or tablet might be cool, but it could be a lot cooler with the right apps. So what? Spend like mad until you find the apps that suit your needs? Nah, just read the weekly Google Play App Roundup here on Tested. We strive to bring you the best new, and newly updated apps on Android. Just click the app name to head to the Play Store.
Sometimes you need to know what's going on inside your phone, and System Panel is one of the apps that helps you do that. However, the original System Panel app hasn't been updated in ages. Now, there's a new version available in the Play Store. It's actually a completely new listing and rewritten app. That means you'll have to buy it again if you had the original.
There will be some concern over the new version so I'll just point out the original System Panel was supported for about 6 years. That's not bad for an app people spent a buck on. The new one has better support for modern versions of Android and has a vastly improved UI. However, changes to the way Android works will limit your ability to track and manage running processes (you shouldn't be "managing" them anyway). You need root access for System Panel 2 to access these tools.
Even without root, there are a lot of cool things to do in System Panel 2. On the main screen you have a dashboard of your phone's current activity. At the top are read-outs of what's going on with your processor, RAM, storage, battery, and network connection. Below that is a historic graph of battery charge and CPU usage. This can be useful troubleshooting an app or performance issues. At the bottom is a panel showing how many apps you have installed, and your device's ID.
Tapping on any of the panels in the main app UI will open additional information. For the top few, you'll get the live streamed data with additional information. Opening the history panel (also accessible from the nav menu) lets you drill down into more historical stats. The device ID panel gives you access to system information like reported specs, network conditions, and location data.
The app manager is one of the most interesting parts of System Panel 2, I think. It has sections for your installed apps, system apps, archived apps, and a permission list. Tapping on any app in the list shows you the package name, install date, last update date, and more. You can archive any app, saving the APK for the current version. The APK is placed on your SD card in a simple folder hierarchy so it's easy to find. With archived apps, you can compare the package stats using the drop down in the app details screen. You can, of course, install those old APKs or export them elsewhere. Note: paid apps can be archived, but the licensing will prevent them from working on devices without a valid account license.
System Panel 2 is still in beta, but it seems really solid for what it is. I'd like to see some widgets, and a few alternative data filters might be nice. If you need a system info app, this one is a good choice and it's free. If you want to remove the ads, it's a $1.99 in-app purchase.
