I'm used to track all my activities using smart watches (now Amazfit TRex 3), and even though it does have Judo as an activity, I cannot practice judo wearing a watch for obvious reasons.

Then I thought, I will just record the training sessions on an app. But the Amazfit Zepp app doesn't allow me to do that, neither does Strava tracks judo...

Do you have any recommendations on apps for tracking training sessions (start/end time and probably a notes section to record what was practiced)?
