Made it so I can run a Tabata without touching the phone :) It runs entirely in your browser — 5 presets (Tabata 20s/10s x8, HIIT 30/15, HIIT 40/20, EMOM, AMRAP) plus unlimited custom work/rest phases with name, color and duration per phase. Audio cues + full-screen mode for the gym TV, and it keeps time locally, so pausing for a phone call doesn't drift the session. After an accidental refresh it restores you to the exact phase and second. Everything is processed on your device — no sign-up, and your saved sequences never leave your browser.
