Log every set, browse 174 exercises in 3D, generate a personalised plan from a short quiz, record your form and get on-device AI feedback. Local-first. Zero servers: your data stays on your devices and in your own iCloud.
Free to use. Pro is $4.99/month with a 7-day free trial.
Real screens from Gym TrAIcker on iPhone — from planning and 3D guidance to progress and privacy.
Built for iPhone first. No accounts, no cloud accounts, no tracking — your training data stays with you.
Log strength and cardio with weight, reps, and RPE for every set.
Curated compound, isolation, cardio, plyometric, and stretching exercises with form tips and a custom RealityKit mannequin demonstrating each one.
A short quiz generates a personalised plan tailored to your goal, experience, equipment, schedule, and focus muscles. Or pick from 7 starter templates and customise.
Record or import a clip for on-device pose feedback. Confidence and coverage checks withhold scores when the camera angle or movement is not reliable enough, so the app does not present false precision.
Open the equipment guide from Home, scan a machine with the camera, and get a cautious match plus usage guidance. You can rescan, bypass, or correct uncertain results.
Animated demonstrations of all 174 exercises with muscle highlighting, a configurable skin tone, and full gesture controls.
Drop a life-size 3D exercise demo in your space. Pinch to scale, double-tap to reset. Optional, no impact on devices without AR.
Start a workout on iPhone and your Apple Watch opens straight to the live set logger — a real workout session that records heart rate and active energy to Apple Health and your Activity rings. Optional breathing-rhythm haptics pulse inhale/exhale cues to your wrist, iPhone-driven over WCSession.
Personal records computed automatically for every exercise: estimated 1RM, heaviest weight, most reps and best volume. Each new record shows how far it beat the previous one.
Body-measurement tracking with a built-in BMI explainer, per-exercise strength charts, a weight trend, and visual delta indicators. Every weight and measurement renders in your units — metric or imperial, app-wide. Optional progress reminders (weekly / biweekly / monthly).
Connect Apple Health explicitly from Settings. Live Apple Watch workouts record heart rate and active energy and contribute to Activity rings.
Use Gym TrAIcker in 31 languages and change language without restarting. Apple Watch follows the language selected on iPhone.
Zero third-party SDKs, no analytics, no trackers, no ads. SwiftData on-device with optional iCloud private-database sync through your own Apple ID. Your data never reaches our servers because there are no servers.
Pro unlocks training plans, analytics, video form analysis, and Watch breathing haptics. $4.99/month with a 7-day free trial.

Anyone training with weights, bodyweight, or cardio who wants a clean iPhone-native log with the option of AI form feedback. Logging is free for everyone; Pro adds guided quiz plans for beginners, plus personal records, unlimited history and progress analytics.
No. Every feature works offline. AI form analysis runs entirely on-device. iCloud sync is optional and uses your own Apple ID.
Free includes the exercise library, manual logging, basic history (last 7 workouts), body measurement entry, and one video form analysis. Pro adds training programs, quiz plans, unlimited video form analysis with on-device narrative feedback, Apple Watch breathing haptics, progress charts, personal records, unlimited history, and data export.
Pro Monthly includes a 7-day free trial for new subscribers. Cancel any time during the trial in iOS Settings → Apple ID → Subscriptions to avoid charges. Trial eligibility follows Apple's standard rules — one trial per Apple ID per subscription group.
Stays on your device. No analytics, no crash reporters, no ads. SwiftData stores your data locally; optional iCloud sync routes through your own Apple ID. Form-analysis clips are saved to the app's private Documents folder and never leave the device unless you explicitly export them.
No. Video form analysis works on every iPhone that meets the iOS deployment target — Vision-based pose estimation and rule-based feedback run everywhere, entirely on the device. Nothing is uploaded and no server is involved.
No. Every other feature works iPhone-only. With a paired Watch, starting a workout on iPhone auto-opens the Watch to the live set logger (heart rate + calories to Apple Health), and the iPhone drives optional breathing-rhythm haptics over WCSession — no third-party connectivity.
No. AR is optional. The 3D mannequin runs in-app on every supported device; AR placement only activates on devices with ARKit and even then is gated behind an opt-in button.
