Iron Tempo

Iron Tempo is an interval training timer that keeps your workout moving so you can focus on the exercise, not the clock. Set the work phase, the rest phase, and the number of rounds. The animated ring counts every second and tells you what is coming next — without you reading a word. When the buzzer goes, switch. When the final round ends, you are done. Build your own circuit Pick from 48 built-in movements — push-ups, kettlebell swings, box jumps, planks, burpees, mountain climbers and more. Set the work and rest duration for each. Stack the rounds in whatever order you like, save the routine, and launch it with one tap next time. Quick-start presets Need a classic Tabata? Two taps: 20 seconds on, 10 seconds off, eight rounds. The app ships ready-made presets for common interval formats so you can start training immediately. Track every session Every completed workout is logged on your device — exercise count, total duration, rounds finished. Open the history screen to see a chart of your training over the past week or month and watch your streak grow. Fully offline Iron Tempo runs entirely on your phone. No account, no login, no internet connection. Your data stays on the device and never leaves it.
