TrAIner: Your AI assistant

Record a set, trim the clip, and get clear form feedback — on device or with AI. Fix what matters before your next lift.

TrAIner is your pocket form coach. Record up to 30 seconds, trim to the working set, and get coaching notes you can act on — without turning every workout into a video project.

HOW IT WORKS • Record with the front camera or import from Photos • Trim with a filmstrip so you analyze only the reps that matter • Analyze on device with Vision pose tracking • Or tap Analyze with AI for richer coach notes (pose data or a short clip — you choose) • Review reps, match %, positives, issues, and pose overlays with timestamps

BUILT FOR THE GYM FLOOR • 139+ exercises with guidance by muscle group • Home dashboard for weekly sets, form focus, and recent sessions • History stays on your phone so you can replay and improve

PRIVATE BY DESIGN • On-device analysis never uploads your video • Analyze with AI only sends what you opt into • No account required to train

PLANS • Free: on-device analysis plus a small lifetime allowance of Analyze with AI • TrAIner Pro: daily Analyze with AI (pose or video modes) • Pro Unlimited: unlimited Analyze with AI Subscriptions are available weekly, monthly, or yearly and auto-renew until cancelled in Settings.

Train with a coach in your pocket. Record the set. Fix the form.
