Most gym apps stop at the front desk. Train Hub starts on the mats — it remembers every roll, maps every technique, and follows you to whatever gym you train at next. Checking in is just the part it does at the door.
Log a roll in plain English — "got swept from half guard twice, caught an armbar off the back." Train Hub pulls out the positions, submissions, and who you rolled with, then builds a scouting report per partner and a leak finder that surfaces where you keep getting caught.
Your note
"Rolled with Diego. Got swept twice from half guard, he kept hitting the old-school sweep. Caught an armbar off the back at the end."
AI analysis
Leak detected
Old-school sweep from half guard — caught here 4× this month.
Every technique you train climbs a ladder — learning → drilling → hitting it live → teaching — inferred from what you log, not a checklist you maintain. See your whole game at a glance and exactly what's ready to level up.
Map a game plan as a decision tree — every reaction branches to your next move. The canvas auto-arranges itself (you never drag boxes), and you can share a read-only link with a teammate or clone someone else's into your own.

Opt in and your training profile is compared — anonymously — against everyone else on the platform. Find out you submit from the back more than most blue belts, or that your guard retention is in the bottom third. Off by default, and only ever shown in aggregate.

Your rolls, your mastery map, your systems, and your rank are tied to you, not your gym. Move across town or across the country and nothing resets — the only thing that changes is whose mats you check into.
Train Hub comes free with your academy's membership. Coming soon to the App Store and Google Play.
