You might know Fitbit from its popular fitness trackers, but the app that powers those devices works well on its own, too. Using your just your smartphone (assuming you meet the minimum hardware requirements), this fitness app can count steps and log activities to help you achieve daily goals. There are also social features, so you can compete against your friends. It's a must-have (really, you must have it) for Fitbit users, but also a smart choice for anyone looking to be more active.

You're terrible at passwords. Don't take it personally! Everyone is terrible at passwords. That's why we all need apps like Dashlane, which generate, save, and replay login credentials wherever they're needed. This smart, cross-platform service makes sure that your passwords, payment information, and other vital information is stored securely but never out of reach. Droid Apps
IFTTT, which stands for "if this, then that," helps you create custom automations between various online services and devices without any coding experience. The mobile app makes it simple to set up these Applets (previously called recipes) on your own or implement any of the community-created ones. IFTTT is particularly great for controlling smart home devices. Droid App
Google Opinion Rewards is appropriately named. Google sends you surveys that ask you about places you've visited recently and you get Google Play Store credit for your participation. Polls don't come in very often, but you can increase your chances of receiving more, by enabling your location and answering surveys quickly and honestly when they do arrive. It's not going to earn you a ton of store credit, but it's enough to purchase an app or an album every so often. To add some perspective, one of our editors has earned about $64 since installing the app in late 2013.
Faxing isn't dead quite yet, but fax machines can safely be left behind thanks to online fax services. Fax.Plus's app is well designed and easy to use. It notably offers a digital signature tool and a contact manager. We like how mobile fax apps allow users to snap a picture of an attachment, attach a fax cover sheet, and send a fax off to a recipient in a few quick actions. Fax.Plus makes this process seamless.

Amazon is the internet's marketplace; the one place where you can buy just about anything—and it's cheap too! On Android, two of our favorite features are the integrated Alexa voice commands and the photo search, which makes it easy to surreptitiously compare Amazon's prices to those of the brick and mortar stores it is killing. Amazon Video-related functionality has been moved over to its own dedicated app, but all of its other consumer services, including Fresh and Restaurants, make an appearance. Prime members rejoice; there's never been a better way to stay connected with your Amazon lifestyle. Droid Apps
Nine is a very reliable email client designed to work with all of your accounts. The clean interface and the optional conversation view make reading and replying to email intuitive. One of the coolest features is the ability to customize the notification actions, including an incredibly useful "Mark as read" option. It isn't cheap, but it's only a one-time $14.99 charge for a much-improved email experience that also integrates calendar, contacts, notes, and tasks functionality. Droid Apps
The Google Play Store gets frequent updates, which is great news. The not-so-great news is that it can take weeks, or for some people even longer, to get the latest iteration. The basic functionality never changes so being stuck on an older version isn’t all that bad. However, we understand the urge to get the latest and greatest version on your device.
What is most impressive about the ESPN Android app is the sheer number of sports it covers. Everything from American football to Brazilian soccer to Indy 500 is available. For those unmissable games, you can set alerts and follow specific matches as they unfold. It also connects you to videos and news headlines, courtesy of the popular sports cable network. Also, check out ESPN's streaming service, ESPN+. Android App

If you use Android, you have a Google Account, and that means you have access to the excellent Google Drive cloud storage service. With Drive, you can easily access synced files across all your devices no matter where you are. With the additional Docs, Sheets, Slides, and Photos apps from Google, Drive is the center of a productivity hub on your Android. Droid App
Tasker is a glorious application if you have the patience to learn how to use the app. What it does is allow users to create custom made commands and then use them in various places. There are many apps out there that have Tasker support and you can even use Tasker to create very complex commands for NFC tags. It’s difficult to truly explain what this app can do because it can do so many things. Between the apps supported, plugins you an add, and the sheer volume of stuff that you can do, there aren’t many apps out there as useful as this one. IFTTT is another excellent automation app. In some cases, it may even be better than Tasker thanks to its simplicity and wide range of uses. New Droid Apps
Firefox is lickety-split fast and has a clean design that is a joy to use. Mozilla makes a big point about how it doesn't collect your data, and we are pleased to see that the app comes with a full complement of security settings—including an option to protect your information from advertisers and a private browsing mode. Like the desktop version, Firefox for mobile has a robust selection of plug-ins, excellent tab management, and a dynamic start page for bookmarks and the latest headlines. You can even sync settings, history, and tabs with the desktop variant
Despite the fact that we are well into the 21st century, paper still persists in offices. But Microsoft Office Lens lets you turn physical documents into digital ones using your Android. It can even capture doodles and notes from a whiteboard. If you want portable document scanning, but aren't keen on getting an Evernote account, this might be the solution for you.
Qustodio is an excellent parental control software that makes it easy to manage your child's mobile activity, especially with its well-designed companion app. Its best features are its browser-independent web content filters and ability to set device usage time limits. Rounding out its capabilities are location tracking, call and SMS logging, and mobile application blocking. Parents will also appreciate the instant device-locking and panic button options.
Although a weather app's primary function is to give an accurate forecast, the presentation of that data is also important. Overdrop manages to accomplish both feats. The app includes helpful timeline-based graphs of temperature, wind, and rain predictions. Furthermore, you can change the units of measurement that the app displays as well as the weather provider. Your choices are Dark Sky or Weather Bit. Droid App

Weather Underground combines a slick design with a focus on really useful weather information. We particularly like the ability to report weather conditions in your area and the extremely useful comparative forecasts that deftly show how conditions have changed since yesterday. With an accompanying set of useful widgets, it's the best weather app on Android. Droid App
