RoundBell: Round Timer

A gym-grade round timer with loud bells, an end-of-round warning, and a display you can read across the room. Boxing, HIIT, Tabata, EMOM, and your own custom timers.

RoundBell is a gym-grade round and interval timer for boxing, HIIT, and everything with a work and rest rhythm. Big numbers, loud bells, and a warning before every round ends, so your hands stay up and your eyes stay off the clock.

Start in seconds with a real built-in library:

• Classic boxing, 12 rounds of 3:00 work and 1:00 rest, plus amateur, speed, and heavy-bag variants
• HIIT intervals like 40/20 and 30/30
• Tabata, the classic 20/10 by eight, and a double round
• EMOM, every minute on the minute
• Bodyweight and core circuits, plus mobility and cooldown flows

Build your own timer:

• Set prepare, rounds, work and rest phases, cooldown, and the bell
• Add as many phases per round as you want for real circuits
• Pick from six bells and a configurable end-of-round warning

During a workout:

• A full-bleed display that scales up on iPad and Mac
• Bell at every change, a warning beep before work ends, and a 3 2 1 countdown
• Haptics and a keep-awake screen, so it works from across the room

Keep going and it adds up:

• Every session is logged with your day streak, totals, and a weekly-minutes chart
• Personal records for best rounds and longest session
• A boxing combo of the day with a coaching tip

Free and Lifetime:

• Free includes the whole built-in library, the full timer, every cue, the log, and up to three saved custom timers
• Lifetime is a one-time $9.99 USD purchase that lifts the cap to unlimited custom timers and unlocks training-log exports to CSV and PDF

Your custom timers and workout history sync across your iPhone, iPad, and Mac with your private iCloud. No account to create, no ads, and no tracking.
