An AI coach that

- Reads your real dataYour sets, sleep, protein and calories — before every reply.
- Daily Tip from THIS morning's dataNot a content calendar. The tip you see is generated today, from your week.

Train with Gym Bud.
Never train alone — even when you train alone. Link with a friend and you'll see each other's workouts, celebrate each other's PRs, and keep each other showing up. That's the whole trick.

React to PRs, nudge a skipped leg day, drop a reaction on a clean check-in. The kind of accountability that actually shows up.
03Help a friend — become a coach
Go past buddy mode. Push programs, review their form notes, run their prep. Your bud, your roster — on a Pro Coach account.
Gym Bud is free for everyone. Running paid clients? Pro Coach is the roster layer — up to 15 clients.
For personal trainersYour content gets attention.
Your content gets attention.
Pro Coach runs the roster.
Built for English-speaking coaches posting real training — form checks, sessions, client wins — who are done running online clients from Instagram DMs and scattered apps.
Clients live in your DMs
Progress pics, “did you train?”, meal questions — none of it is a system. It’s an unpaid second job.
Programs die in PDFs
You write solid programming. They screenshot it once and ghost the plan. You can’t see who actually lifted.
Views ≠ retained clients
High-engagement training content fills the top of the funnel. Pro Coach is how you run the roster after they say yes.

FAQQuestions,
Questions,
answered straight.
Still wondering? Email mattyofttraining@gmail.com. The dev reads every one.
I've never lifted. Is this for me?
Built for exactly that. Tell MyCoach you're starting from zero and it assumes nothing — it builds your first program, explains every exercise, and answers the questions you might not want to ask out loud. Day one is what it's best at.
Do I need to know exercise names or gym jargon?
No. Ask in plain words — "the machine where you push with your legs" works fine. The coach understands, teaches you the proper name, and never makes you feel behind.
Is FitSync on the App Store and Google Play?
Yes — both, live now. Download free on the App Store (iPhone & iPad) or Google Play (Android). You can also install the web app from your browser. Same FitSync, same account — your data syncs across every platform.
Does it actually work offline?
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.
What's a PWA — do I need the store apps?
FitSync is also a Progressive Web App — full-screen and offline-capable from the browser if you prefer. But the recommended path is the native apps, live on the App Store and Google Play. Same product either way.
How does MyCoach use my data?
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 →
Can I cancel anytime?
Yes — one tap from Menu → Premium. No win-back screen, no "are you sure" gauntlet. Your plan stays active until the period ends, then you drop back to free Core. Your data stays put.
I'm a coach. How does that work?
Grab a Pro Coach Account (€29.95/mo, up to 15 clients, free trial where available). Each client connects with one 6-character code. Push their programs, see their logs, comment on check-ins in real time. MyCoach steps back — you're the voice. More on Pro Coach →
Is my data private?
GDPR-compliant. Stored encrypted on Google Firebase (EU SCC). Never sold, never shared with advertisers. Delete your account from inside the app and it's wiped within 30 days. Full privacy policy →
