The more you scroll, the harder the math gets
PlugBrain is a free, open-source Android app that puts a quick math problem between you and the apps you waste time on. The more you scroll, the harder the math gets. Step away and it gets easier. No ads, no tracking, no account, and no internet permission.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
