About this app

25 years on the mats taught me one thing: beeps are confusing.

Hi, I'm Keisuke. I've been training BJJ since 2001 and have run my academy, Enso Jiu Jitsu, since 2012. I built this BJJ timer because I was tired of the two biggest mat-side headaches:

The "Beep Guessing Game": Is that the one-minute warning or the end of the round?

The "Mat Math": Fiddling with menus just to find the right round times for different ranks.

Whether you're running a grappling session, a Brazilian Jiu Jitsu class, or solo drilling, this roll timer is designed to stay out of the way. One tap, clear voice cues, and you're back to focusing on the training — not the clock.

Why this BJJ timer works:

Clear Voice Cues: No more guessing beeps. The app tells you exactly when there is a minute left and when the round is over — perfect for Jiu Jitsu training and grappling rounds.
One-Tap Rank Presets: Tap your rank (White through Black Belt) and start instantly. Includes standard BJJ match times like IBJJF.
High-Visibility: Bold, high-contrast numbers you can actually see across a sweaty gym.
Zero Distractions: No ads, no tracking, and no fluff. Just a solid Jiu Jitsu timer for your training.

Tested daily on my own mats. If you find it useful, thanks for supporting a small business owner. See you on the mats! 🥋
