Gym Timer Oji

Gym Timer Oji is a clean, no-nonsense interval timer for HIIT, Tabata, boxing rounds, circuits, and any structured workout. Build a routine once, hit start, and put your phone in your pocket. It keeps perfect time and cues every transition, even with the screen locked. BUILT FOR REAL WORKOUTS Structure a full session the way you actually train: Prepare, then Work and Rest repeated for your cycles, all repeated for your sets, then Cool down. On the last cycle of each set the normal rest becomes a longer "rest between sets," and the final set ends straight into cool down with no dangling rest. Set any duration from seconds to an hour, 1 to 99 cycles, and 1 to 99 sets. SAVE YOUR OWN PRESETS Create and name as many workouts as you like. Everything is stored on your device, so your presets are always there and always instant. No sign-up, no sync, no connection required. CUES YOU CAN TRAIN TO Independent beep and vibration toggles. Choose your beep (soft, sharp tick, boxing bell, or triple countdown) and vibration strength, and set how many seconds before each change the warning fires. The beep never fights your music: when other audio is already playing it is suppressed automatically, and the app always mixes with your music. It never pauses, ducks, or takes over playback. RUNS IN YOUR POCKET, SCREEN OFF A timestamp-based clock stays accurate through backgrounding and lock, so cues land exactly on time while the screen is off. Better for your battery and your eyes.
