xTimer - HIIT & BPM Timer

xTimer is a simple timer for anything you split into blocks of time:
basketball drills, HIIT, Tabata, jump rope and running,
but also Pomodoro study sessions, step-by-step routines and cooking.
HIIT intervals, a BPM beat, chained timers and more: 6 modes in one app.
No sign-up. Works offline.

■ 6 modes

[Interval]
A HIIT / Tabata timer that repeats Work and Rest for a set number of rounds.
- Set Work seconds, Rest seconds and rounds (e.g. 20s x 10s x 8)
- For basketball suicides / sprint-and-rest conditioning
- Also 50/10 study blocks or 4s/4s breathing exercises
- 10-second READY before the first round
- Countdown beeps in the last 3 seconds, sounds on phase change and finish
- WORK / REST shown with screen colors

[Beat]
A metronome-style timer that plays a beat at a steady BPM.
- Set BPM, duration and sound
- For jump rope tempo, running cadence (e.g. 180 spm) and dribbling / ball-handling tempo
- Works as a metronome for instrument practice

[Beat Chain]
Chain beats at different BPMs.
- Build rhythm patterns beat by beat, or step up the tempo every few seconds
- Repeat for a set time or until you stop
- For jump rope speed work and cadence changes in interval runs

[Chain]
Link timers of different lengths into one routine.
- Warm-up → main set → cool-down in a single run
- Shooting drills: 1 min shooting → 30s rebounds → 1 min shooting…
- Pomodoro: 25 min focus → 5 min break, repeated
- Step-by-step routines such as "hold 1 min → wait 5 min"
- Stretching / yoga flows, cooking steps (boil 8 min → rest 2 min)

[Timer]
A simple countdown in minutes and seconds, up to 99:55.
- 24-second shot clock practice, 10-minute quarters
- Cooking, power naps, timed presentation practice
- A looping alarm rings when time's up. Stop it whenever you want

[Stopwatch]
A stopwatch with 1/100-second precision.
