Impulse

Impulse is a modern brain-training app built around short games, puzzles, and mental tests. It has a clean, mobile-friendly design, which makes it easy to open when you only have a few minutes.

This is definitely one of the more casual apps on the list. It doesn’t feel as “serious” or practical as other options, but that’s not necessarily a bad thing. The simplicity of it makes it a good alternative for people who want something that’s quick and easy.

The app and its design are pretty straightforward. You can open it during a break, complete a few challenges, and move on. Still, that doesn’t mean it lacks the features you need. There are over 35 games you can try, and over 200 puzzles to solve. Plus, you can get a more personalized plan, so you focus on the puzzles you want.
