Ready90

Ready90 turns your phone into a movement coach for soccer players who want to keep their knees healthy.

Film yourself doing a drop jump, squat, cut, or shot, and Ready90 analyzes the knee mechanics that sports-science research links to ACL and knee injuries — then gives you clear, plain-language feedback in seconds.

WHAT IT CHECKS • Landing / plant knee bend — absorbing force, or landing stiff? • Knee cave (valgus) — do your knees track over your toes or collapse inward? • Left / right symmetry — is one leg doing more of the work? • Vertical jump height — track your explosiveness over time • Rep counting with per-rep form flags

HOW IT WORKS

1. Pick your movement (drop jump, squat, single-leg squat, cut & plant, kicking, and more)
2. Prop up your phone and film a few reps
3. Get a simple form score and coaching cues — tap "Advanced" for the detailed angles and research targets

DAILY READINESS Log a 30-second check-in (sleep, soreness, energy) for a daily readiness score, so you can spot when you're pushing too hard.

TRACK PROGRESS Every session is saved on your device — watch your knee mechanics, symmetry, and jump height trend over time.

PRIVATE BY DESIGN Everything runs on your phone. Your videos and results never leave your device — no account required.

Ready90 provides general coaching and training guidance based on published movement-screening research (LESS, limb-symmetry norms). It is not a medical device and does not diagnose, treat, or prevent injury. Always consult a qualified professional for medical advice.
