Minuum is a tiny predictive keyboard for Android

Are you tired of losing half of your smartphone’s screen to the keyboard? Well, here comes Minuum.

Minuum shrinks the keyboard down to no more than a near-single line, and use a predictive algorithm to ease the text input. If the tiny version is just too tiny, the latest update lets you come back to a full-sized version.

Minuum on Google Play ($4 or €2.90)
