Record the set. Fix the form.
TrAIner is a focused form coach for iPhone. Record up to 30 seconds, trim the working set, and get on-device pose analysis or optional Analyze with AI — with clear positives, issues, and pose overlays. Your video stays on your phone unless you choose to send a short clip for AI.
On-device VisionAnalyze with AIPrivate by design
On-device or AI coach
Pose tracking on your phone, or Analyze with AI for richer notes — you choose.
Progress you can replay
Keep analysed sets, jump to timestamps, and compare sessions over time.
Screens
From the gym floor to coach notes.
Record, trim, analyse, and review — the same flow you will see in the App Store listing.
Flow
Three steps, built for the gym floor.
Home, trAIn, and Settings stay out of the way so recording and feedback stay fast.
trAIn
Record or import a clip, scrub the filmstrip, and lock a 30-second window.
- Configurable countdown
- Trim before analyse
- On-device or Analyze with AI
Analyse
On-device pose tracking classifies the exercise and scores form cues — or send pose data / a short clip for AI coaching.
- Joint angles and timestamps
- Positives and issues to fix
- Pose overlay on the clip
Home
Revisit recent sets, browse the library, and track weekly form focus.
- Local recording library
- Weekly sets and issues
- Coverage across 139 exercises
Features
Built from the app itself.
Every section here maps to a real workflow inside TrAIner — no marketing filler.
Capture and trim
Selfie camera with a recording timer, Photos import, and a filmstrip so you analyse only the working set.
Form feedback
Depth, torso lean, elbow path, and more — written as clear coaching notes you can jump to in the clip.
Exercise library
Browse by muscle group, open how-to guidance, and confirm the move after recognition.
Private by design
On-device analysis never uploads video. Analyze with AI only sends what you choose — pose data or a 10-second clip.

Keep analysed sets on device, review match %, and track issues flagged across the week.
