Pay Once.
Train Forever.
A native iOS personal trainer powered by science. Live Activities on the Lock Screen, HealthKit on Finish, and a coach that knows your sport. No subscription.

You're paying $180/year
for workouts that aren't yours.
Subscription Trap
Fitbod: $14.99/mo. JEFIT: $12.99/mo. Nike+: $14.99/mo. That's $180+/year for cookie-cutter programs.
Generic Plans
Same plan for everyone. Doesn't know your body, your equipment, your goals. You're following someone else's program.
No Science
Most apps use bro-science. No real research behind the rep ranges, rest times, or progression models they recommend.
From clueless to confident
in 1 minute.
Tell Us About You
Tell us your sport, body, and goals. 9 quick steps. Free forever.
AI Builds Your Plan
AI builds your plan from 17 peer-reviewed studies. 8 sports. Fat-loss protocol when you ask for it.
Train With Confidence
Live Activity ticks down on your Lock Screen between sets. HealthKit logs the session when you finish.
While they charge monthly,
you pay once.
Everything you need.
Nothing you don't.
AI-Personalized Plans
AI tunes plans to your sport — gym, running, yoga, combat, CrossFit, calisthenics, sport, rehab. Ask for fat loss and the coach loads an evidence-based protocol. Not a template.
Live Activities & Widgets
Rest intervals tick down on your Lock Screen and Dynamic Island. The Today widget shows your streak. Drop your phone in your bag — the timer keeps going.
17 Scientific Studies
Every rep range, rest period, and progression model is sourced from peer-reviewed meta-analyses. Real evidence — not bro-science.
HealthKit, Built In
Every finished workout writes to Apple Health. Fitness rings, Activity, third-party apps — they all see it. No exports, no accounts.
Questions? Answered.
What happens after 500 AI plans?
500 plans means you can regenerate your workout every week for almost 10 years. Your existing plans never expire — they're saved locally forever. Most users need fewer than 50 plans total.
Is this really one-time? No hidden fees?
Yes. $5.99 (R$29.90 in Brazil) once. No subscriptions, no trials that auto-renew, no premium tiers. You get everything.
How is it personalized vs Fitbod or JEFIT?
We use AI tuned by 17 peer-reviewed meta-analyses, ask about your sport, body, equipment, and specific goal — then build a plan that matches YOUR profile, not a generic template. Fat-loss goal? You get an evidence-based fat-loss protocol on top.
Why iOS only?
Trainer Gym AI is a SwiftUI-native iOS app — Live Activities, widgets, HealthKit, and AppIntents are core to how it works. We rebuilt from scratch to focus on doing iOS exceptionally well.
