Description
PlugBrain is an app that encourages regular breaks from distracting apps by blocking access at scheduled intervals.
To regain access, you’ll need to solve a math challenge that adjusts in difficulty: the more frequently you use the apps, the harder the challenges become, but the longer you stay away, the easier they get.
**Features**
• No ads
• No internet required
• Blocks distracting apps
• Unblock apps by solving math challenges
• Difficulty increases with frequent use, decreases with focus
**How to use**
• Grant all required permissions
• Select distracting apps
• Choose your focus interval
• Stay focused ;)
