Finally something different from endless BJJ videos 😄 Love the way Underhook makes learning feel simple and organized. Great job!

### 5/5 — Your Jiu-Jitsu Coach, Anytime

*2026-09-27*

Love this app! It makes learning Jiu-Jitsu easy, fun, and really enjoyable.

### 5/5 — Easy and fun learning

*2026-09-26*

Started BJJ recently and this app is exactly what I needed. There’s so much to remember after class, and Underhook makes it much easier to understand and review techniques. Really enjoying it so far! 🥋

### 5/5 — Very useful for beginner 100%

*2026-09-25*

BJJ is not only about physicality, but about mental work as well. An average amount of training is enough to develop your physical abilities, but not enough to fully develop your mental game – obviously, unless you’re a professional who trains for several hours every day. But with Underhook, I can train my brain even while I’m waiting for an appointment to start. And oh boy, it’s beautiful and easy to use! 10/10.

### 5/5 — Dangerously addictive!

*2026-08-22*

At first, I was skeptical - Duolingo for BJJ? But after a few days, it’s become a really handy tool for developing a “BJJ mindset.” Top-level work from the dev—the usability and attention to detail are just top-notch. Thank you for doing this!

### 5/5 — Very unique

*2026-07-29*

Love this for refreshing my memory of sequences and situations on the mat! Highly recommend this app👍
