Corner Timer: Boxing

Boxing Round Training Timer

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Corner Timer is a focused round timer that helps boxers stay with the rhythm of each session and concentrate on movement and breathing. Train at your level, from beginners learning the fundamentals to experienced boxers building demanding routines. Keep your favorite music playing and move with a ring timer that signals every round. Adjust the session and its five-level intensity rating to match your condition, then review your training history and progress graphs at a glance. Large controls remain practical with gloves or sweaty hands. Oversized numbers make the time and current round readable when an iPhone or iPad is placed across the gym. Red identifies training, blue identifies rest, and a high-contrast pause state keeps every phase clear.
