Why it works
Less input. More useful history.
Log gi and no-gi sessions.
Save class time, rounds, and technique notes after training. Keep rolling, drilling, and competition sessions in one history.
One log per class
Compete with people who know your game.
Weekly leaderboards, streaks, and training-partner context give the room a shared reason to show up.

Turn your training history into a profile.
Public stats, clips, medals, and mat hours become the link that belongs in a grappler profile.

Public profile
The link that proves you train.
Every grappler gets a clean public profile: hours, belt, gym, weekly shape, clips, medals, and the receipts that usually disappear into chat threads.

Keep what matters after class.
Mattime records how long you trained, what kind of work it was, who was there, and what showed up in rounds. That is enough signal to guide the next session.

FAQ
Common questions
Is Mattime only a timer?
No. It starts with fast mat-time logging, then adds weekly goals, friends, gym leaderboards, technique notes, public profiles, clips, and competition context.
Can I use it if my gym is not on Mattime?
Yes. You can track your own sessions immediately and add gym or partner context as your circle joins.
Does this replace my notes app?
It can. Mattime is built for the specific parts of grappling notes that matter later: time, rounds, partners, techniques, clips, and progress.
Where is it available?
MatTime is available on iOS through the App Store and on Android through Google Play.
