"Unlock it naturally but training your mind"

Reviewed by / Feb 08, 2013

Solve simple equations and unlock your phone

Unlock Your Brain is a puzzle game for Android, a brain trainer application that improves your math skills in a simple but extremely efficient way.

How does it work? The app replaces your lockscreen with an arithmetic operation, which requires you to solve it in order to use your phone properly. This way, if you unlock your phone about 50 times a day, you will solve math operations 50 times a day, which will definitely help your concentration and logic skills improve.

Set the Unlock Your Brain as default launcher and start training your brain every day, even if you don't want to. The only disadvantage is that with the Samsung Galaxy Tab, the lock screen is not viewed properly, some of the numbers aren't clear and this should be fixed inmediately, although it works well in other devices.

UNLOCKYOURBRAIN is the developer of this helpful mind trainer, a useful math app that even has other features

* Still thirsty for more? Put in an extra workout by challenging yourself or others in Practice Mode

* Includes Addition. Subtraction, Multiplication, and Division available for purchase in the app.

    I wanted to improve my french and Chinese (amongst other things) but noticed some errors between the words and the translation. That's very tricky and unfortunate. More comments would include being able to see a full story/definition of the word when learning it, being able to hear the words be said when we learn it or practice, and not simply be taught new words every time I go to the app to prac
