your journal stays on device
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.
- Right after class: Keep the whole session together. Round count, training partners, and duration stay attached to the session while the details are still fresh.
- Before the next class: Walk in with one thing to test. Your latest lesson becomes a clear focus, ready when the next round starts.
- 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. You can export your training journal in a structured format at any time.
What happens if I delete the app?
All stored data is permanently erased from your device, and it cannot be recovered unless you have an iCloud backup enabled.
What iPhone do I need?
Any iPhone that can run iOS 18.2 or later. There is no iPad version.
What languages does it support?
English, French, German, Portuguese, and Spanish.
What is changing in the redesign?
The screens on this page preview it. It arrives as a free update to the same app — nothing new to buy, and the journal you start today carries over.
Ready for your next session?
Log it while the details are still fresh.
