OCON Spatial is free to download. OCON Premium is $4.99 per month after a 7-day free trial, and the coaching features described below require an active subscription. Your iPhone or iPad camera just became your toughest, smartest training partner. OCON Spatial watches every rep you take and tells you the truth about your form — instantly, privately, and without a trainer in the room. ON-DEVICE BY DESIGN Movement analysis runs entirely on your device using Apple's Vision body-pose framework, built into iOS. There is no third-party AI provider, no cloud inference, no analytics and no advertising. No video, image or workout data is ever uploaded, and there is no server or account database behind the app. Your reps stay yours. FORM INTELLIGENCE, NOT A REP COUNTER Live pose detection tracks joint angles, rep depth, elbow position and spine alignment in real time, then converts your session into a single number: your WQ (Workout Quality) score — a blend of form precision, safety index and tempo consistency. CATCH IMBALANCES AS THEY HAPPEN A live balance panel compares your left and right sides rep by rep and flags asymmetric positions while you lift. During hinge movements like deadlifts and rows, OCON Spatial flags rounded-back positions the moment they occur, so you can self-correct on the next rep. YOUR HALL OF FAME Every rep that meets the form threshold is automatically clipped and saved to your private Hall of Fame — a highlight reel of your best training moments, stored on your device and built entirely from your own performance. HONEST PROGRESSION Elite Progression bars for Form Precision, Power/Strength and Consistency start at zero and move only from real workouts you log. No fluff, no fake milestones — just an honest record of your improvement. WHO IT'S FOR Solo lifters, home-gym owners, and anyone training without a coach watching their back. If you track your metrics like a Whoop or Strava user and want that same discipline applied to your form, this is your tool. SUBSCRIPTION DETAILS OCON Premium: $4.99 per month, with a 7-day free trial for new subscribers. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Sign in with Apple is the only sign-in method; no email or password is required.
