Hear the coach
This is what it sounds like.
Real lines the coach says in a workout, in the voices that ship in the app. Press play.

How it works
Three steps. No tapping.
- 01
Put your phone away
Start your workout, pop in your earbuds, start your music if you like, and pocket the phone. The microphone is on only while a workout is running.
- 02
Say “185 for 8”
Plain words, between sets, like you would to a spotter. It reads the set back so you hear what was logged. Wrong? Say “no, 190” and it fixes it.
- 03
The coach handles the rest
It runs your rest timer, tells you the next weight and reps, says “go” when you are ready, and sets up your program for next week.
Typing vs talking
A logging app waits for your thumbs.
SweatCall is built for your ears, so the workout never turns into phone time.
Typing sets into a logging app
- Logging a set
- Unlock the phone, find the exercise, enter weight and reps.
- A mistake
- Find the entry and edit it.
- Rest
- Look at a timer.
- Next week
- You decide what changes.
Talking to SweatCall
- Logging a set
- Say “185 for 8.” It reads the set back.
- A mistake
- Say “no, 190.”
- Rest
- It counts it, tells you the next target and says “go.”
- Next week
- It proposes changes from what you lifted. You accept or skip each.
Everything in the app is still there to tap when you want to. Voice is the fast way, not the only way.
What you get
Everything the log, nothing in your hands.
Hands-free logging
Weight, reps and effort, said out loud. No unlocking, no typing with chalky fingers.
Rest and targets, spoken
You hear your next target after every set and a short “go” when rest is up.
Learns your voice
Teach it your voice once and it skips the people on the next rack.
AirPods or speaker
Plays through whatever you wear and falls back to the phone speaker when nothing is connected. Your music ducks, then comes right back.
Weekly program review
Each week it looks at what you did and proposes changes. You see each one and accept or skip it.
Apple Watch
A companion app for your wrist: cues for your rest and your heart rate while you lift.
Widgets and Live Activity
Start today’s workout from the Home Screen, and follow your set and rest on the Lock Screen and in the Dynamic Island.
Built for a loud gym
It hears you. Not the room.
The workout loop is made for earbuds, a pocket and a busy floor.
- Your voice only. Teach it three short lines and it ignores other people talking nearby.
- AirPods or speaker. Use whatever you have; the coach follows your audio route.
- Corrections are natural. “No, 190” or “that was 7 reps” fixes the last set.
- Rest runs itself. A big glanceable timer and the next target, with a spoken “go” at zero.
Programs and your week
Next week, already planned.
Follow a built-in program or build your own. After each week, SweatCall looks at what you actually lifted and proposes changes to your program. You see what would change and decide.
- Weekly review. Accept or skip each proposed change.
- One history. Every set, session and personal record in one place, with a summary after each workout.

- Voice print never leavesIf you teach it your voice, the voice print lives on your device only: never uploaded, never synced, left out of backups, and one tap to forget.
- Only your sets syncWeight, reps, exercise and time go to our servers so your data syncs and your weekly review can be written. For the review, no audio and only your first name go to Anthropic’s Claude.

Questions
FAQ
What is SweatCall?
An AI coach for strength training that lives in your ear. You talk, it listens: say “185 for 8” and the set is logged. It runs your rest, tells you the next target and reviews your program each week.
When can I get it?
SweatCall is not on the App Store yet. It is in testing on iPhone. Join the early-access list and we will email you once when it is ready.
Is it free?
Yes, for lifters. There is no paid tier. If you add a human coach, coaching subscriptions carry a 5% + 30¢ service fee, and only those.
Does it work with music?
Yes. Your music keeps playing: it ducks while the coach talks and comes right back.
Does it work in a loud gym?
You can teach it your voice once, and it then ignores other people talking nearby. A very loud room can still make a word hard to hear, which is why every set is read back and a wrong one is fixed by saying “no, 190”.
Do I need AirPods?
No. Audio goes to AirPods or any headphones you wear, or to the phone speaker when none are connected.
What happens to my audio?
Speech is recognized on your phone. Audio is not stored and stays on your device, except in a live coach session you book. See the privacy policy for exactly what is kept.
What about Android?
iPhone comes first. Android is planned for later.
I joined the waitlist. How do I get off it?
Use the contact form and give the address you signed up with, and we will delete it.
