Your coach's voice
Your coach records a short voice note for every movement and every form fault. The moment the camera spots the fault, you hear your own coach's voice.
THE COACH THAT SEES EVERY REP
CAMERA FORM ANALYSIS · NO SIGN-UP
Your phone's camera watches your set, measures your form and tells you what to fix on the next rep. Measurement, not guesswork.
Coming soon to the App Store and Google Play01 — FORM ANALYSIS
The form engine reads your elbow angle, bar path and tempo on every rep. The moment the set ends, your score is ready — along with exactly what to fix on the next rep.
02 — COACH CONNECTION
Your coach follows every set from their own dashboard: writes your programme, tracks your progress, corrects your form remotely. It costs the gym nothing; Klan S simply connects the two of you.
03 — AI COACH
Take a photo of your meal and the calories and macros land in your log within seconds. The AI coach rewrites the day's plan around that day's training load.
Training, nutrition and body tracking are free — no sign-up needed. Coach connection, unlimited form analysis and the AI coach come with Premium.

04 — WHAT SETS US APART
The camera station at the gym, your coach and your phone work as one system. Six things that make Klan S different:

Your coach records a short voice note for every movement and every form fault. The moment the camera spots the fault, you hear your own coach's voice.

Across nine movements it counts every rep, scores your form as a percentage and warns you on safety faults. Video is processed on your phone and never sent to a server.

Clean sets done on camera at the gym station earn the gold “Verified” seal. The camera verifies reps and form; you enter the weight. Take your place on your gym's verified-set board.

Scan the station's QR code: the weight from your programme is ready, the camera counts the reps, and the set logs itself.

Your coach puts you in a team of 2–6. The week only counts when everyone hits their goal — you carry each other, and nudge whoever's behind with one tap.

A new league starts every Monday. Your sets, gym visits and training days earn points. Joining is optional; the table shows only your first name and last initial.
