No ads before your workout, no account, no signal needed — and Pro is a one-time purchase, not a subscription for "one timer".

✓ Ready-made presets: Tabata (20/10 × 8), EMOM 10, AMRAP 20, Boxing (3 min / 1 min × 12)
✓ Fullscreen timer — huge auto-sizing digits, background color switches with the phase (work = red, rest = green, or your own colors), circular progress ring, round counter, next-interval preview
✓ Voice coach — text-to-speech announces each exercise by name; 3-2-1 countdown beeps and interval-change tones
✓ Music ducking — beeps briefly lower your music instead of pausing it; Spotify keeps playing
✓ Survives screen-off and Doze — foreground service + wakelock; time computed from elapsed-time deltas, so it can't drift even if the system delays a tick
