Technique library

Every technique in one place: notes, positions, tags, photos and clips. Fuzzy search finds it even when you misspell it.

๐ŸŽฌ

Clips, cleaned up

Trim a clip, crop away black bars, speed it up. Keep just the part that matters.

๐Ÿ““

Study notebooks

Turn a seminar, a course or a month of classes into a notebook: your notes and clips in order, linked to your library.

โฑ๏ธ

Class planner & round timer

Plan a class in timed segments and share it as a link. A loud round timer for drilling and sparring.

โœ…

Training habits

Track mat time, drilling, mobility, whatever you want to keep doing. Streaks and a year-at-a-glance heatmap.

โ˜๏ธ

Your camera roll stays clean

Everything lives in your private cloud account, on any of your devices. Works offline and syncs later.
