## What is CornerBell Timer?

English supported. CornerBell is a focused combat sports timer for boxing, MMA, kickboxing, Muay Thai, BJJ, circuit training, and HIIT. Start fast with built-in presets or create custom timers that match your gym, class, or personal workout flow.

A large circular timer, clear ready-round-rest states, session history, and training statistics help you stay locked in during training. On iPad, CornerBell Pro unlocks Full Screen Gym Mode so the timer is easy to read from across the room. With AirPlay or an external display, you can show Gym Mode on a TV or second screen in supported environments, making it easier for a class or training room to follow the timer together.

CornerBell Pro is a one-time purchase that unlocks unlimited custom timers, voice announcements, extra sounds, custom remaining-time alerts, and unlimited history. Most data stays on your device. No ads. No interruptions. Just training.
