## Description

Knee plumb on your own photo: see whether your saddle needs to move forward or back. Plus live fitting with a voice coach as you pedal. No subscription, no cloud.

Your bike fit — live, voice-guided, on your own bike.

RoadFitter draws your skeleton LIVE over the camera image and coaches you through your fit with voice guidance — while you sit on your bike and pedal. No uploads, no waiting, no subscription.

HOW IT WORKS
• Prop up your phone side-on, get on your bike, start pedaling
• The voice guides you: calibration, measurement, results
• Knee, torso, shoulder and elbow angles — measured live across ~30 pedal strokes, never a single snapshot
• Clear recommendation (e.g. "raise saddle ~10 mm"), then re-test instantly: before/after to the degree

THREE MODES
• Live Fit: guided fitting with a voice coach — our core feature
• Manual Measurement: all angles in real time while you adjust your bike
• Video Scan: record a short clip, full analysis of every pedal stroke

SADDLE FORE/AFT — YOUR DIGITAL PLUMB
• On your own photo, at the forward crank position: a plumb line dropping from your knee
• Slide it with the arrows from the knee joint to the front of your knee and see whether it sits over the ball of your foot
• Deliberately no traffic light: there is no universally correct saddle position — you decide
• Re-measure after adjusting and the change is shown in millimeters

FOR EVERY BIKE
Road (aero & endurance), gravel, TT/triathlon, city, step-through, spin — and kids' bikes with a safety-first approach.

YOUR FITS ARE KEPT
• Every measurement is saved per bike — with photo, angles and knee plumb
• Find your way back after transport, a saddle swap or a rebuild

HONEST & PRIVATE
• The knee angle is the only scientifically validated, injury-relevant value — and that's exactly what we tell you. Everything else is guidance based on comfort and riding style.
• Angle targets apply regardless of gender (current evidence).
• Your measurements and videos stay on your iPhone. No cloud, no account.
• No black box: your angles are pure geometry — transparent math, not AI hype.

A professional bike fit costs $150–400. RoadFitter brings the key adjustments home — as often as you like, for all your bikes.

Note: RoadFitter is not a medical device and does not replace a professional bike fit or medical advice. If you're in pain, see a professional.
