I've been working on PlugBrain, an open-source Android app that helps reduce screen time by blocking distracting apps. Instead of simply locking you out, PlugBrain makes you solve math puzzles to regain access.
PlugBrain uses math challenges as a barrier. The difficulty increases as you use distracting apps more often, and decreases if you stay away.
The app is GPL3-licensed and available on GitHub. Still early, so I'd love feedback on the code, usability, and whether the idea feels useful or annoying in practice.

PlugBrain began as a personal tool I built to manage screen time for myself and my loved ones. Later, I shared the source code with a group of students as a teaching project, showing them how real-world app development works: from development, writing tests, to setting up CI/CD automation, to collaborating on an open source project.
What started as a personal experiment and a learning exercise eventually grew into something bigger, and today PlugBrain is fully open source.
