shapeblinder

This game is basically your perfect choice if you are looking to take a break from this complex, attention-seeking world, as it returns to a very basic concept everyone is familiar with: shapes.

In this game, there's a shape hidden on the screen and you need to find it. If you tap inside the shape, you'll feel some haptic feedback or vibration, and with the help of this feedback (and some imagination), you'll be able to find the hidden shape.

The app ships with no analytics, ads or in-app purchases, and it's completely open-source. You can find the source here:
