Brushy

A toothbrush timer app for iOS and Android. No smart toothbrush required.

Brushy tracks timer sessions — not brushing correctness, technique, or health outcomes. A circular countdown timer divides your session into four equal visual segments. At each boundary, the app delivers noticeable haptic feedback. When you stop, a quick modal captures what else happened: floss, tongue scrape, mouthwash, bleeding.

Sessions are recorded to a local JSON vault and backed up automatically via iCloud (iOS) and Android Auto Backup. The Calendar screen shows your full session history. The Toothbrush screen tracks your brush head age and reminds you when it's time to replace it.

One intent. No accounts. No subscriptions. No coaching. Just a timer.
