Your pocket-sized stage coach + gym mirror assassin. You prop your phone up, hit poses, and the app becomes a live, savage, real-time posing judge: it analyzes symmetry, angles, lat flare, lines, transitions, and presenceâthen barks cues, counts hold-time, auto-captures your best frames, and builds routines you can drill like combos.
Think: âIron Mirror + AI coach + stage simulator + progress studioâ all in one.
⸝
The Core Experience (what it feels like)
1. Set phone down (tripod, bench, water bottleâwhatever).
2. Tap âPOSE NOWâ.
3. Choose:
⢠Division (Menâs Physique / Classic / Bodybuilding / Bikini / Wellness, etc.)
⢠Pose (Front Double / Side Chest / Back Lat Spread / Ab & ThighâŚ)
4. You get a live camera view with:
⢠A clean overlay guide (lines, angles, symmetry bars)
⢠A âpose lockâ reticle that turns green when you nail it
⢠A score that climbs in real time
5. The app says stuff like:
⢠âChest UP. Left elbow +6°. Flare lats. HOLD.â
6. When you hit the sweet spot:
⢠Auto-capture the best photo + 2s video clip
⢠Save it into your Progress Gallery and Best Takes
Itâs a video game⌠but the final boss is your own physique.

⢠shoulder-to-waist
⢠chest-to-waist

⢠âBest Poseâ leaderboard for YOU:
⢠âYour strongest pose is Side Chest.â
⢠âBack Double is improving fastest.â
⸝
5) Progress Studio: Auto-Captured Best Frames

⢠best still
⢠short clip
⢠metadata: pose, score, angles, lighting condition
⢠Comparison tools:

⸝
The AI Engine (what it actually does)
You can build this with proven computer-vision building blocks.
A) Pose & Joint Tracking
⢠2D pose estimation for joints (shoulders, elbows, hips, knees, ankles)
⢠Optional 3D refinement with depth (newer phones help a lot)
B) Body Segmentation
⢠Separates you from background â cleaner metrics and overlays
⢠Helps estimate:
⢠lat spread silhouette width
⢠waist line consistency
⢠stance width
C) Pose Matching + Scoring
⢠Each pose template is a set of:
⢠joint angles (e.g., elbow flexion)
⢠relative positions (e.g., elbow height vs shoulder height)
⢠symmetry constraints (left vs right)
⢠âline rulesâ (spine, hip tilt, knee lock)
Score approach (simple + effective):
⢠Compute a vector of normalized features:
⢠angles, ratios, relative distances
⢠Compare to template:
⢠weighted deviation penalties
⢠Add stability:
⢠penalize shake/wobble over time
⢠Output:
⢠Pose Score (0â100)
⢠âFix listâ ranked by impact
D) Smart Cues (the âcoach voiceâ)
Instead of generic tips, cues are computed from the biggest current error:
⢠âRaise left elbowâ (largest deviation)
⢠âRotate torso slightly rightâ
⢠âOpen chestâ (shoulder roll + sternum lift proxy)
⢠âShift weight to rear legâ (hip/ankle alignment)
