The all-in-one coaching platform built for lifters who actually train. Workout logs, macros, body analytics — plus MyCoach, an AI forged from 70+ years of bodybuilding wisdom that reads your data before it speaks.
Seventeen seconds. One workout. MyCoach reading your log, replying with the protocol fix. The loop most lifters take twelve weeks to figure out — running on autoplay because no one taps anymore.
Two thousand beta testers, 4.8 / 5 average rating, zero refund-emails about MyCoach. Here's a slice.
"Added 10 kg to my bench in twelve weeks. MyCoach kept telling me to drop volume the weeks I felt the worst — and it just worked."
"I deleted MyFitnessPal, Strong, and Notes. FitSync is the only app I open before the gym now."
"The Daily Tip alone makes it worth it. Like getting a text from a coach who actually remembers what you did Tuesday."
Most AI coaches give you forum advice with a smile. MyCoach pulls your last 12 sessions, your macro trend, your sleep — then answers. Trained on the books and articles that built every champion since Arnold.

FitSync is a Progressive Web App — a full-screen, offline-capable app that installs from the browser. No App Store account, no download wait, no review delays. Native iOS and Android versions are coming soon — the PWA gets you the same experience today.
Yes. Once installed, your logs, food diary, and workout history are cached locally. Open the app on a basement gym Wi-Fi blackspot and it still loads. Syncs to the cloud the moment you're back online.
Native builds are in development for both platforms. The PWA experience matches them feature-for-feature today — install it, your data carries over automatically once the native versions ship.
When you message MyCoach, your recent workouts, macros, sleep notes, and goals are sent at query time to generate a context-aware reply — then discarded. We've opted out of all model training. Your data is never sold, never used for ads. Full AI disclosure →
Yes — one tap from Menu → Premium. No win-back screen, no "are you sure" gauntlet. Pro stays active until the period ends, then you drop back to Core. Your data stays put.
