Grove is a very simple but highly effective habit tracking app. The concept is that you plant a tree; that tree represents your habit.

When you repeat that habit day by day, the seed grows into a giant tree. However, if you don't do that habit (relapse), you start over again from the seed phase, and then you have to redo it and grow it again.

It is a very fun and effective way of tracking your habits. Make sure to subscribe for future apps that are useful like this.

FUTO Keyboard — this is the most free and privacy-respecting keyboard app that I have ever used. Its main feature is, of course, privacy, which means that no data is collected or shared. The voice typing feature of this keyboard is one of the most accurate voice typing assistance tools that I have ever used in a keyboard.

The keyboard is also very customizable, and you can even create your own themes to customize the interface of the keyboard.
