Cornerman: Boxing Round Timer

Prop your phone up and train. Big colour-coded rounds you can read from across the gym, clear bells, and it works on silent. Free, no ads.

Cornerman is the round timer you prop up and actually watch.

Set your rounds, your work and rest, tap start, and the whole screen turns into the clock. Work is red, rest is green, the round number is big, and the colour climbs up the screen so you always know where you are without squinting. A bell on every round, and a 10 second heads-up before each one finishes.

No ads. No subscription. No account. It runs completely offline.

A few things people like about it:

• It's built to be seen. The timer is the whole screen, so it's easy to read mid-round from across the room. • It plays on silent. The bells still come through with your ringer off. • It keeps the screen awake. Prop it on a bench or the floor and it stays on through your round, so you never miss a bell. • You can share a session. One tap turns a finished workout into a clean card for the gym chat.

Built for boxing, Muay Thai, MMA, kickboxing, and timed HIIT rounds.
