Sparring Rounds

Step into the ring with Sparring Rounds, the premium interval timer designed for fighters, martial artists, and heavy-bag enthusiasts.
Most modern workout timers are cluttered with messy menus, subscriptions, and distractions. Sparring Rounds strips all of that away, replacing it with a gorgeous, gritty, skeuomorphic design that feels like a physical piece of vintage gym equipment. Built with worn wood, glowing digital LED displays, and a rusty metal boxing bell, this app is designed to get you out of your phone and into the zone.

AUTHENTIC GYM VIBE
A stunning, old-school aesthetic that looks and feels like a real boxing clock.

FULLY CUSTOMIZABLE INTERVALS
Easily configure your workout in seconds. Set your total number of rounds, round duration, and rest periods to match your exact conditioning goals.

IMMERSIVE AUDIO CUES
Keep your eyes on the bag, not the clock. Features a real gym bell for round transitions, a distinct warning clap to let you know when to empty the tank, and a 3-2-1 countdown beep before the bell strikes.

CRISP TAPTIC FEEDBACK
Every button press triggers Apple’s native Taptic Engine, giving you a satisfying, tactile "click" that makes the app feel like physical hardware.

ALWAYS READY
Sparring Rounds automatically saves your last-used configuration to your device. Open the app, hit play, and instantly start your workout without having to re-enter your settings.

Whether you are shadowboxing, hitting the heavy bag, rolling on the mats, or running a high-intensity interval (HIIT) circuit, Sparring Rounds is the only clock you need in your corner.
Put your wraps on. Hit play. Get to work.
