TempoSpan

Keep track of time with a focused set of offline tools. Use the stopwatch to start, pause, resume, reset, and record laps. Compare split times with fastest and slowest markers. Create countdowns from one second to 99 hours, name them, pause them, add a minute, and restart a completed run. A clear on-screen completion state works even when sound is off; optional system sound and vibration can be enabled. Build interval plans with 2–12 named stages and 1–50 cycles. Follow stage progress, see what comes next, skip a stage when needed, and review stage results. Save and reuse presets. Rename, copy, reorder, and archive saved countdowns and interval plans. Review timer history, including mode, start time, duration, pauses, laps, or stage results, and remove one record or clear the list. Runs and preferences are saved on this device. Return to a running timer after leaving the app; elapsed time is recalculated from saved timestamps. Timers do not start until you choose Start. No account or internet connection is required for timing.
