The round timer that feels like pro fight equipment.
Southpaw is a boxing, MMA, Muay Thai and HIIT interval timer built for the gym floor: giant digits you can read from across the room, a bell that rings even with your iPhone on silent, and zero clutter between you and the next round.

• Huge high-contrast countdown, color-coded phases (get ready / work / rest)
• Classic bell on round start and end, 10-second warning clacker
