Google Opinion Rewards is easily one of the best free Android apps in the Google Play Store. To use this app, you simply download and install it, then open it one time. After that, the app will periodically notify you to ask you some questions. You’ll get credit for use in the Google Play Store every time you answer a survey. That credit can go toward buying yourself apps or games in Google Play. It’s a great way to expand your collection without spending real money. At worst, everyone should have this app installed.

Your Gmail inbox is not secure. Use ProtonMail instead. This encrypted email platform offers a range of pricing options, including a free tier, so you have no excuse not to join. Security and privacy features aside, ProtonMail works like any other email app. Make sure to also check out ProtonVPN for securing your network traffic; it's an Editors' Choice for free VPNs.

TickTick is among the best to do list apps on Android. It works a lot like Wunderlist, actually. You can make lists, share tasks with other people, organize your tasks in various ways, get reminders, set recurring tasks, and more. It’s also highly modular. That helps with organization. The widgets aren’t half bad either. There is a pro version, but it adds things like calendar support and other additional features. The free version of this is far above what most other to do list apps offer. It’s also clean, easy to use, and it’s great for small teams or family use. It’s technically not a free app. However, the free version functions better than most free to-do list apps. Don’t worry, you won’t need the premium version except in extreme cases. Droid Apps
We use Best Apps Market because it highlights trending content, has a huge range of categories, and many of the apps are reviewed and tested. If you are focusing on games, you won’t find a better app than Fetch because it allows you to search by multiple traits. For example, you can filter the results down to search for something as specific as, “3D horror shooter with great music where you have to defend and use resources.” There are over 100 traits to help you find the right title.

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.

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
