MatTimer - Countdown
Jiu-Jitsu and MMA timer
Free · Designed for iPad. Not verified for macOS.
Work, rest, repeat. Numbers you can read from across the mat, a bell you can hear over the noise, and an Apple Watch app that keeps up.
A round timer for the mat. Set your work time, your rest time and how many rounds — then put the phone down and train.
MatTimer counts the round in numbers big enough to read from across the room, and colours the whole screen so you know where you are at a glance: green for work, red for rest. A ten-second lead-in gives you time to touch hands before the first round starts.
WHAT IT DOES
• Work, rest and round count, all adjustable
• A bell at every round change, so you never have to look
• An optional ten-second warning before each round ends — set it for work, rest, or both
• Save the sessions you use often and switch between them in a tap
• The screen stays awake while the timer runs
ON YOUR WRIST
A full Apple Watch app, not a remote control. Start, pause and stop from the watch, with the same round readout and the same colours. Set your rounds there too.
ON YOUR HOME SCREEN
A widget shows the round you are in and the time left, without opening the app.
IT KEEPS YOUR PLACE
Leave the app mid-round and it picks up exactly where it should — right round, right phase, right second. While you are away, notifications tell you when each round turns over.
BUILT FOR TRAINING, NOT FOR SCROLLING
No account. No subscription. No ads. Nothing to read. Open it, start it, roll.
Ratings & Reviews
A rebuild, inside and out.
• A new app icon
• The Apple Watch app is now a single screen — the clock stays in front of you and the controls moved into the toolbars, so the time is visible at the moment you reach for Start
• Rounds on the watch are set with the Digital Crown
• Redrawn for iOS 26 and watchOS 26
Fixed
• Returning to the app mid-round could resume in the wrong phase, or leave Stop tappable while the timer was idle
• The countdown could open a round on the wrong second and skip a number catching up
• The progress fill could stall between rounds until you paused and started again
• Settings and saved sessions could be lost when upgrading from an older version
• Widget buttons that did nothing are gone
