BrushFirst

BrushFirst is an iPhone app that ties tooth brushing to phone access. Using Apple's Screen Time technology, it blocks apps you choose, such as social media, games or streaming, until you complete a guided brushing session. The App Store listing is in French and calls it a brushing timer and app blocker.

You set separate morning and night windows, and when a window opens the selected apps stay locked until a two-minute timer finishes. A Live Activity shows progress on the Lock Screen, and the app tracks streaks, milestones and weekly completion insights. A snooze option allows one delay without losing the streak, and scheduling adapts if you skip mornings, nights or both.

BrushFirst is a commercial app from the developer Oussama Elhaidi, free to download with in-app purchases. It suits people who forget to brush or who lose track of time scrolling, and who want a firm nudge rather than a reminder.
