## What is Callus?

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.

Muscle-Ups · Handstands · The Snatch · Double-Unders · Wall Balls · The SkiErg · and many more

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.

MEMBERSHIP
Your first session is free, with no payment details needed. Membership gives you a coach for every session, conversation included, with fair-use limits shown in the app before you buy. Top-ups are available for big months.

Payment is charged to your Apple Account at confirmation of purchase. The membership renews monthly unless cancelled at least 24 hours before the end of the current period, and renewal is charged within 24 hours before then. Manage or cancel in your App Store account settings.

Callus is a training tool, not medical advice. If something hurts, stop and see a professional.
