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 presence—then barks cues, counts hold-time, auto-captures your best frames, and builds routines you can drill like combos.
Think: “Iron Mirror + AI coach + stage simulator + progress studio” all in one.
⸻
The Core Experience (what it feels like)
1. Set phone down (tripod, bench, water bottle—whatever).
2. Tap “POSE NOW”.
3. Choose:
• Division (Men’s Physique / Classic / Bodybuilding / Bikini / Wellness, etc.)
• Pose (Front Double / Side Chest / Back Lat Spread / Ab & Thigh…)
4. You get a live camera view with:
• A clean overlay guide (lines, angles, symmetry bars)
• A “pose lock” reticle that turns green when you nail it
• A score that climbs in real time
5. The app says stuff like:
• “Chest UP. Left elbow +6°. Flare lats. HOLD.”
6. When you hit the sweet spot:
• Auto-capture the best photo + 2s video clip
• Save it into your Progress Gallery and Best Takes
It’s a video game… but the final boss is your own physique.

The Killer Features
1) Real-Time Pose Coach (the main weapon)
• Live skeletal tracking + body segmentation
• Pose templates with adjustable tolerance for your proportions
• Angle + symmetry correction
Example: front double biceps:
• elbow height match
• shoulder roll + chest lift
• hip alignment + knee lockout
• lat flare/waist taper emphasis
• Hold Timer + “Stage Ready” timer
• 3s → 10s → 20s holds
• fatigue training: “Keep it clean under burn.”
Modes
• Practice Mode: cues + corrections
• Silent Mode: only visual feedback (for gyms)
• Judge Mode: zero hints—just score + capture (brutal but real)
• Mirror Mode: left-right flipped like an actual mirror
⸻
2) Routine Builder + Transition Trainer
Bodybuilding isn’t just poses—it’s flow. This makes routines drillable like choreography.
• Drag-and-drop routine timeline:
• Pose → transition → pose → transition
• Add:
• Music track (optional)
• Mandatory pose list (auto-checks compliance)
• Stage walk-in / turn / quarter turns
• AI Transition Smoothness Score
• detects wobble, rushed movements, posture collapse
• Dynamic Time Practice
• “Hit pose at beep, hold through second beep.”
⸻
3) Stage Simulator (hardcore realism)
Turn your garage or gym corner into “show day.”
• Lighting presets:
• harsh overhead stage lights
• warm auditorium wash
• side-light drama for classic physique
• Background options:
• black curtain
• stage silhouette
• Audio:
• crowd murmur
• judge callouts (“Number 12—front and center.”)
• Pressure mode:
• random pose callouts
• limited time to hit pose clean
⸻
4) Flex Analyzer: Symmetry, Lines, Ratios
Not “body shaming.” This is objective geometry + consistency tracking.
• Symmetry map: left vs right delts/arms/legs alignment
• Line quality: spine neutral, scap control, posture collapse detection
• Ratios (approximate, trend-based):
• shoulder-to-waist
• chest-to-waist
• quad sweep appearance (pose-dependent)
• “Best Pose” leaderboard for YOU:
• “Your strongest pose is Side Chest.”
• “Back Double is improving fastest.”
⸻
5) Progress Studio: Auto-Captured Best Frames
This app should be a mini photo studio.
• Auto-capture triggers when:
• pose is within threshold AND stable for X ms
• Saves:
• best still
• short clip
• metadata: pose, score, angles, lighting condition
• Comparison tools:
• swipe compare week-to-week
• “same pose, same camera distance” lock mode
• Export:
• coach package (zip/video sheet)
• social-ready crop presets
⸻
6) Pump-Up & Warmup Mode
You’re about to pose? Cool. Let’s get that pop.
• Quick pump timers:
• shoulders/arms pump circuit
• chest activation
• lat “open-up”
• Bands-only presets
• “Don’t gas out” pacing: short bursts + rest control
⸻
7) Coach Mode (remote feedback without pain)
• Share a session link / package
• Coach can:
• draw on frames
• drop time-stamped notes
• set “pose targets” for next session
• Athlete can replay with overlays and coach notes
⸻
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 → 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)
• “line rules” (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 (0–100)
• “Fix list” ranked by impact
D) Smart Cues (the “coach voice”)
Instead of generic tips, cues are computed from the biggest current error:
• “Raise left elbow” (largest deviation)
• “Rotate torso slightly right”
• “Open chest” (shoulder roll + sternum lift proxy)
• “Shift weight to rear leg” (hip/ankle alignment)

• syncing your gallery across devices
• sharing coach packages (opt-in)
• Clear controls:
• delete session
• export all
• disable cloud entirely
• Ethical guardrails:
• avoid “body rating” language
• use “pose quality” and “symmetry” and “execution”
• include reminders about rest and injury prevention

Signature Feature Ideas (to make it legendary)
“GREEN LOCK”
When your pose is correct and stable → screen corners glow and the app captures automatically. You’ll chase that lock like a PR.
“POSE PR”
Tracks your best score per pose and makes you beat it like lifting numbers.
“FLEX FATALITY”
At the end of a routine, it generates a highlight reel of your best frames and transitions—instant dopamine.
⸻
Want the next step?
If you want, I can also give you:
• a full pose template sheet (angles + checks for each pose)
• a complete screen-by-screen wireframe spec
• the exact scoring feature vectors for 10 classic poses
• a technical build plan (Core ML / TFLite pipeline + on-device performance strategy)
But even as-is: FLEXFORGE AI is a complete, buildable product concept that would slap unbelievably hard for bodybuilders.
