Yogger

Yogger is an AI movement analysis tool from Yogger Corporation (incubated at Dartmouth's Tuck School of Business) that replaces expensive lab equipment with one phone, giving physical therapists, chiropractors, personal trainers, and strength coaches quantifiable joint tracking and range-of-motion assessment.

Core capabilities

• Markerless joint tracking: no markers or sensors needed; a phone/tablet/webcam automatically overlays a skeleton and tracks joints
• Automatic angles and ROM: measures joint angles and range of motion for shoulder/hip/elbow/knee/ankle automatically, with CSV export
• Guided assessment scoring: a built-in library of standard movements (overhead squat, single-leg squat, lunge, shoulder flexion-rotation) auto-scores in about 60 seconds
• Professional video analysis: frame-by-frame slow motion, side-by-side comparison, path and speed tracking, drawing annotations, and voiceover commentary
• Branded PDF reports: one-click reports with stills, angles, and scores carrying your organization's brand, easing communication and record-keeping
• Client and remote management: athlete profiles, a Dropbox for client-uploaded videos, task assignments, and progress history

Use cases Physical therapists, rehab therapists, chiropractors, personal trainers, and strength coaches for in-clinic assessment, on-site video analysis, and remote/asynchronous movement coaching; also fits sports researchers and educators needing exportable data. If you only want free slow-motion line drawing, skip it.

Unique strengths Peers like Onform, Kinovea, and Coach's Eye each have their own focus, while Yogger's difference is integrating AI auto-scoring + ROM data + branded reports + client management into a business loop rather than plain slow-motion drawing. Note the disambiguation: this entry is the rehab movement analysis product at yogger.io, not same-named tools.

Editorial verdict 4.8 stars on iOS and 4.5 on Google Play with a solid clinical reputation — a PT with 23 years of experience called it one of the best advances in the field in recent years. Deductions for inconsistent pricing messaging (homepage from $99/month vs pricing page from $159/month), the controversy over frame rates capped below 30fps, and weaker Android stability; those sensitive to data trustworthiness should be careful.
