Gym owners don't buy software because software is interesting. They buy time back.

Shrimp is built around a single idea: reduce operational friction for gym owners, coaches and members. Every feature, every workflow, every screen is judged by that.

Every class moves you closer to the next stripe.

Members keep a training journal and watch their progress build. Coaches and admins see the same record, so promotions are fair and easy to track.

  • Log every classRounds rolled, techniques drilled, who you trained with and how it felt.
  • See your trendsClasses, rounds and hours by week or month, plus the techniques you practise most.
  • Belt history that stays accurateCoaches see classes since the last belt and stripe. Admins approve promotions and every one is on record.
