A Progressive Web App (PWA) for counting sounds — claps, knocks, or any sharp noise. Works in your browser on any device and can be installed as a home-screen app on Android and iOS.
| Feature | Details |
|---|---|
| Generic mode | Counts any sudden, loud sound event without setup |
| Matched mode | Record a 3-second reference sample; only sounds that match the recording are counted |
| Large counter | Prominent number display, easy to read at a glance |
| Manual adjust | Tap − / + to correct the count at any time |
| Target | Set a goal number; the background smoothly transitions from green → red as you approach it |
| Sensitivity & interval | Adjust how easy it is to trigger a count and the minimum time between events |
| Offline support | Cached by a service worker — works without internet after first load |
| Installable | Add to home screen on Android (Chrome) and iOS (Safari) |
