Jiu-Jitsu Round Timer

Jiu-Jitsu Round Timer is a focused round timer for BJJ — set rounds, rest, and warning alerts, tap start, and train. No accounts, subscriptions, or clutter. Just a large, mat-readable countdown with audio and haptic cues so you never break flow to check the screen.

Configure every session

Adjust round duration, rest periods, number of rounds, and warning time. Changes take effect immediately — even mid-session. Three built-in presets — Rolling, Competition Prep, and Positional Sparring — cover common gym formats. Save your own presets and reload them with one tap.

Cues you can hear across the room

• Distinct tones for round start, round end, warning, and session complete
• Haptic feedback on every phase transition
• Large countdown ring color-coded by phase: gold for rounds, teal for rest, red for warnings, green when finished
• Round progress dots show where you are in the session
• Portrait and landscape layouts; screen stays on while the timer runs
