NeWaza

NeWaza is a judo study app you can use without signing in.

Browse throws, pins, chokes, and joint locks with short coaching notes. There are basics (principles, etiquette, ranks, terms), training ideas (warm-up, uchi-komi, randori), a round timer, a terminology quiz, and a simple training check-in.

Favorites and check-ins stay on your phone. Core features work without internet.

This is a study reference. Train under a coach, follow dojo rules, and release on tap or matte.
