Dropbox pioneered the personal cloud service, where all your stuff would be available no matter what device you were using. On Android, it holds its own—even against the highly integrated Google Drive. Dropbox can also act as a seamless backup for your images, automatically uploading every photo to the cloud. It even includes some light image editing tools. If you're the type of person with lots of files already stored in Dropbox, this app is a must-have. Android App Microsoft Edge allows you to easily sync web pages, bookmarks, and browsing history between your Android device and the Edge browser on your desktop. Top features of the mobile browser include an integrated reading view, news ratings (handled by NewsGuard), and a content blocker (powered by Adblock Plus). You can search with Bing using your voice or by selecting a photo, as well as earn points via the Microsoft Rewards program. Both Microsoft Edge's dark and light theme look elegant and are easy to navigate.
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. Droid App
