For Android, this is the best I can find for any martial art. On PC, the best martial art options are TKD3D and Aikido3D.
The app is great love it, just waiting on the rest of the Kata videos
Can't wait to see the Kata videos finished up and uploaded to the app.
Admin , please add in Newaza and Tachiwaza filter option in the techniques portion please..
Edit: fix the bug. Thank you. After the update, the app just open the initial help pages, the app do not open. I use this for refresh my mind on techniques
Judo info .all you need for practice & theory
Well Structured
Not bad. A few suggestions: let user create their own sets. Add sorting and grouping for techniques (alphabetical, grade, newaza, tachiwaza, etc). Use better quality GIFs. Let users add notes on the techniques.
Since the name sound many times different then how it reads i suggest add a sound option to terminology saying the term for those like to know how it pronounced correctly.
Very good and improving over time
