A clean, ad-free BJJ rolling timer for the mat. Open it, start it, and roll — no popups, no banner ads, no subscription prompts. Six 5-minute rounds with 1-minute rest. Standard IBJJF format. Audio bell on round start and end. Runs in any mobile browser — no app installation required.
Five minutes and one minute rest is the standard because it mirrors IBJJF competition exactly. No reason to deviate from the standard unless training for a specific belt or competition format. Adjust rounds up for longer sessions or down for shorter mat time.

❓ Frequently Asked Questions
Why do most BJJ timer apps have ads?
Most timer apps are built to monetize through ads or in-app purchases. This web-based timer has no ads because it doesn't require app store distribution or the business model that comes with it. Open the URL in your browser and bookmark it — it's always free.
Does the timer work on a phone while rolling?
Yes. Keep the browser tab open and the screen active. The audio bell functions even if the screen dims (as long as the tab stays active). For the longest sessions, plug the phone in to prevent battery drain and place it where the audio is audible from the mat.
Does this timer work offline?
The timer requires an initial page load but the countdown logic runs entirely in the browser — no continuous internet connection is needed once the page has loaded. If you lose connection during a session, the timer continues. Reload the page if connectivity drops before starting.
What is the best way to set up a phone timer at a home mat?
Place the phone at ear level (not on the floor where audio is muffled) in a corner of the mat. Bluetooth speakers improve audio dramatically. Set phone volume to maximum and ensure silent mode is off. Landscape orientation gives a larger display if you want to see the countdown between rounds.
