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 Apps
Let's be honest: Tasker is very intimidating. But we recognize that this is perhaps the most powerful app available in Google Play. With it, you can script basic actions for your Android to perform when specific conditions are met—like flash the LED when you receive a text message. Learning to use something this powerful can be tricky, but the rewards seem worth it.
Initially, we weren’t going to put any launchers on this list. Nova Launcher seems to be extend beyond what normal launchers are. It’s been around for years, it’s been consistently updated, and thus it’s never not been a great option for a launcher replacement. It comes with a host of features, including the ability to backup and restore your home screen set ups, icon theming for all of your Android apps, tons of customization elements for the home screen and app drawer, and more. You can even make it look like the Pixel Launcher if you want to. If you go premium, you can tack on gesture controls, unread count badges for apps, and icon swipe actions. Those looking for something simpler may want to try Lawnchair Launcher, Hyperion Launcher, and Rootless Launcher as well. Droid App
