About
Learn the hard stuff.
Film an attempt. Callus spots the one thing that matters most right now, gives you something to try, and watches the next one. If it worked, you build on it. If not, it finds another way in. Over time, Callus coaches you towards virtuosity.

HOW IT WORKS
• Film one attempt from the side, or choose a video you already have.
• Your coach picks out the one fault worth fixing first, in the words a coach would use, and shows you the moment it happens on your own footage.
• You get one cue to try. Film again, and your coach tells you honestly whether it changed: better, the same or worse.
• If a cue doesn't land, you get a different one, a drill or a simpler version — never the same instruction louder.
A COACH THAT REMEMBERS
Your coach keeps notes on every movement you work on: what you're practising, the cues that worked, the ones that didn't, and what to check next time. Come back next week and pick up where you left off.
SKILLS ARE EARNED
Progress is the work itself: attempts, breakthroughs and the faults that stopped showing up.

What's New in Callus
2.1
October 20, 2026
Come back to a session after a break and your coach picks up where you left off. Once a cue has worked on one rep, your coach can offer a short set to check the change holds. Joining and topping up are smoother too.
