## What is Southpaw?

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.

TRAIN WITHOUT LOOKING
• Huge high-contrast countdown, color-coded phases (get ready / work / rest)
• Classic bell on round start and end, 10-second warning clacker
• Countdown beeps and haptics so you feel the round coming
• Sound keeps working in the background and on silent
• Screen stays awake for the whole session

SET UP IN SECONDS
• Boxing, MMA, Muay Thai and HIIT presets, one tap to start
• Quick config: round time, rest time, rounds
• Pause, resume or reset with gloves on — huge touch targets

SOUTHPAW PRO (one-time purchase, yours forever)
• Save unlimited custom presets with your own name
• Advanced round patterns: pyramids and ladders with per-round preview
• All sound packs: Classic Bell, Air Horn, Beep
• No subscriptions. No ads. No account. Ever.

Whether you are on the heavy bag, sparring, doing pad work or grinding through a HIIT circuit, Southpaw keeps the rounds honest.

Your fight. Your rounds.
