One simple training loop

Log the session. Choose what to try next.

Capture the rounds, partners, and one useful detail while they are fresh. The app brings that focus back before you train again.

  1. Right after class: Keep the whole session together. The lesson, your training partners, and time on the mat stay attached to the session while the details are still fresh.
  2. Before the next class: Walk in with one thing to test. Your latest lesson becomes a clear focus, ready when the next round starts.
  3. Weeks later: See your training become a pattern. Sessions stop blurring together as your journal connects decisions, people, and progress.

Before you download

The questions people ask first.

Is it really free?

Yes. Jiu-Jitsu Logs is free on the App Store — no subscription, no in-app purchases, no ads.

Do I need an account?

No. There is no sign-up and no remote profile. Open the app and start logging.

Where does my data live?

On your iPhone. It is stored with iOS data protection and encrypted while your device is locked, and the app never sends it anywhere.

Can I get my data out?

Yes. Backup & Restore saves your whole journal to a portable file you can keep anywhere and restore anytime.

What happens if I delete the app?

All stored data is permanently erased from your device. To restore it later, save a backup file first or keep an iCloud backup enabled.

What iPhone do I need?

Any iPhone that can run iOS 18.2 or later. Coach’s Note needs Apple Intelligence on iOS 26 or later. There is no iPad version.

What languages does it support?

English, French, German, Brazilian Portuguese, and Spanish.

What is new in version 2.0?

A redesign around one habit: write down what happened, then carry one focus into your next class. Quick Log saves a session in one sentence, Log Again repeats a past class, and Progress covers 4 weeks, 12 weeks, or all time. It is a free update, and your existing journal comes with you.

Ready for your next session?

Log it while the details are still fresh.

Free on iPhone. No subscription. No account.
