- Anyone who misses the distinct rhythm of military PT and group runs
[Key Features]
3 Whistle Patterns
- Simple Beat — A basic mode that sounds evenly at your set BPM. Perfect for finding your initial cadence.
- Military Style — An accented tone sounds every N beats. Beep Beep Beep Beep-beep! Use it to break up your intervals or as pace checkpoints.
- Interval — Set different BPMs and durations for high-intensity and low-intensity segments. Train in intervals purely by sound, without needing a timer.
[Real-time BPM Adjustment While Running]
Move the slider, and the change is applied instantly on the very next beat. No need to pause or restart.
[Pace Input → Automatic BPM Recommendation]
Enter your target pace (min/km), and the app automatically recommends a BPM that matches cadence standards.
For example, a 5:00/km pace recommends 173 BPM, and a 4:00/km pace recommends around 180 BPM.
[Volume Control]
Finely adjust the volume to a comfortable level that isn't harsh on your ears.
[Simple Black & White Design]
A minimalist, clutter-free black and white UI.
Check your BPM at a single glance while running.
[Running and Cadence]
Cadence refers to the number of steps you take per minute (counting both feet).
Generally, 160–180 BPM is known to be ideal for maintaining an efficient running posture.
Shortening your stride and increasing your stride rate reduces the impact on your knees and joints while improving energy efficiency.
pppp is the simplest and most intuitive tool for this cadence training.
