Google Opinion Rewards
While most of what we recommend as essential is free, some apps will cost you a few bucks. If you shelled out some cash for everything on your list it will be costly. But Opinion Rewards can help cover the cost of these future purchases. This app is a must-download because it is free money. The app pushes surveys to you now and then, most of which take a few seconds to complete. Once done, the app rewards you with $0.10 a dollar of Store credit. That can spend on anything in the Play Store, including these essential apps, movies, TV, books, or music.

Snapseed
That photo you snapped looks okay. But what if you want to crop it or add an artsy filter. Before you post it on your social network of choice? Most phones come with rudimentary image editing capabilities, but Snapseed is better. This app has a clean, touchscreen-friendly interface that makes it easy to tweak saturation, brightness, and other essential photo qualities. You can also crop, rotate, add text, and more. Many phones support RAW photo capture now; Snapseed can also open those files. That means your edits will be much more high-quality than reprocessing an already compressed regular JPEG file. It has been updating Snapseed consistently; it is still completely free.
