Free Sound-Activated Punch Tracker | Coach

1 May 2026

Added a live Punch Speedometer and changed everything to track Punches Per Second (PPS) rather than Punches Per Minute (PPM). I also added a MAX PPS for each round so you can later check to see your maximum bursts of speed with various combinations during each round. It's a lot more fun now! What MAX PPS are you capable off?

Redesigned the look and feel for easier Round/Time/Rest selection.

24 Apr 2026

Added an early first round pace check designed to give you an idea of how you're doing relative to the Level set in Settings. Coach will let you know you if your starting pace is at the right level or if you need to lift it.

Added some personality to Coach 😂.

7 Apr 2026

Added mid-round voice cues to help you pick up the pace when you slow down.

5 Apr 2026

Added end-of-round countdown so you know to go hard in the last 10 seconds of each round.
Added 4-minute rounds and 3-minute rest intervals to support longer conditioning and mixed-intensity training.

1 Apr 2026

Added spoken announcements for the next round so you stay ready.
Improved the share button to make saving and sharing results easier.
Refined PPM target ranges to better match realistic training levels. Pro Boxer level is now very challenging - I dare you to try it!
