iOS · Voice-first strength coach

Put in an earbud.

Your coach takes it from there — calling your sets, hearing what you lifted, logging it hands-free.

Hear it

A live workout session.

Tell your coach what you did, ask for a rest timer — it’s all by voice, and your hands never leave the bar.

Your plan

Built from your answers, not a template.

Answer a few questions once — the coach handles the rest.

  • Built around your goal, schedule, and equipment
  • Programmed around anything that hurts
  • Adapts when life gets in the way
  • Weights progress from your own logged sets

Free includes one plan generation. Pro and Premium are unlimited.

Coaches

Pick your coach.

Four quick questions match you to one — hear them below. Choosing your own is a Pro feature.

Classic

Precise and to the point

“Bar path drifted forward. Reset your brace and take it again.”

  • Coaches with short, technical cues
  • Talks in real numbers — sets, reps, load
  • Keeps rest tight, no filler between sets

Supportive

Steady and encouraging

“That was a good set. Take your time — no rush on the next one.”

  • Checks in on how you’re feeling
  • Eases off before you burn out
  • Steady encouragement, zero pressure

Energetic

Loud and in your corner

“Two more. You’ve got these — let’s go!”

  • Drives the pace of every session
  • Loud in your corner on the hard sets
  • Celebrates every rep you earn

Premium — the coaching brain

It remembers. And it shows its sources.

Every injury, preference, and PR — kept, and coached around.

Bench 60 → 72.5 kg. Progression from your own logged sets

Answers come from published research — sources shown, never guessed.

You ask

“Should I train to failure on every set?”

Your coach answers

Not on every set. Stopping one or two reps short keeps most of the growth stimulus at a fraction of the recovery cost.

FAQ

Frequently asked questions.

Anything else — cancelling, deleting your data, getting in touch — lives on the support page.

Coaching & plans

How does the coach build my plan?

It reads the profile you fill in — goals, experience, how many days you train, how long a session runs, your equipment, and any injuries — and checks that against a curated strength-training research corpus before proposing a week. Nothing is saved until you accept it.

Can it really log my sets while I lift?

Say the set out loud — “135 for 8” — and it records it, starts your rest timer, and tells you what is next. You can also ask it to swap an exercise or skip ahead without stopping.

What happens if I close the app mid-workout?

Nothing is lost. Reopen it and the session resumes on the same exercise and set, with your logged sets intact — leaving the app does not end a workout.

Devices & connection

Do I need AirPods?

No. Any earbuds — or the phone’s own mic and speaker — work. Earbuds are just more comfortable with a bar in your hands.

Is there an Android version?

Not yet. GymSync is iOS-only today.

Does it work without signal?

Logging works offline. Voice coaching and chat need a connection.

How do I switch between pounds and kilograms?

Settings → Units. Weights are stored independently of how they are shown, so past logs re-display in your choice too — nothing is converted or rounded away.

Billing & data

How do I cancel?

Subscriptions are handled by Apple, not by us: on your device, open Settings → your name → Subscriptions. You keep the paid features until the period you have already paid for runs out, and your data is untouched either way.

How do I delete everything?

Settings → Account settings → Delete account. It erases your profile, plans, training history, and conversations straight away, and it can’t be undone.
