Rolling drums count your round down. A brass bell — a real one, with a hammer on a spring — rings you in and out. Wood clappers call the last ten seconds, the way a boxing gym always has. Nothing fades or toasts. Everything has mass, springs, and sound.
One machine, one screen. Errors are jams. Settings are on the back, where a machinist would bolt them.
Every mechanical event has a strike you can feel — phone and wrist. The screen is confirmation, not the message.
Bells cut through your music with the phone locked and in your pocket. Interrupting actions are holds and drags, never taps.
No account. No network. Your rounds live on your phone and nowhere else.
| Event | Sound | Feel |
|---|---|---|
| ROUND BELL | Brass strike, five-second tail, pitch-shifted so triples never phase | Full strike + 300 ms decay |
| 10 S WARNING | Wood clappers ×2 — the authentic boxing call | Double knock |
| DIAL DETENT | Ratchet tick | Sharp transient per step |
| ROUND PUNCHED | Metal punch through steel | Heavy stamp |
| PAUSE | Power-down whir; the lights sag half a stop | 240 ms fading rumble |
Every sample is synthesized in the app from partials and filtered noise — no audio files, no downloads. If the app is killed mid-session, scheduled system alarms carry every remaining bell through Silent and Focus. The clock itself runs on absolute dates: lock it, background it, take a call — it does not drift.
