Coming to the App Store
Built around one person: you.
Your lifts, recovery, bloodwork and cycle in one place, read by a coach that knows your history and builds or moves your plan only when you approve it.
See how it works
Your records stay on your phone.
Chalk, steel, and the next set.
What it does differently
Four things you will not find in a workout log.
Your period, beside your training.
Phases on your charts and your lab results, and your own pattern after three cycles.
Your bloods, beside your lifts.
Lab results in your lab's units and range, read against your training and weight.
A coach that asks first.
It reads your own history, then shows you the change before anything in your plan moves.
Your records stay on your phone.
What leaves, and when, in one plain list.
Log
Every set, quietly kept.
Log a set in two taps, let the timer run, and finish with a plain summary of what you did.
Log the set.
Reps and weight fill in from last time, so you change only what changed. Bench press, 3 x 5 at 75 kg.
Rest, timed.
The timer starts when you save the set, and a notification tells you when it is done, even with the phone in your pocket.
Workout saved.
Workout saved. 5 exercises, 18 sets. Bench press is up 2.5 kg on last week.
Your numbers
Numbers that move, read plainly.
Lifts, weight, check-ins and lab results sit side by side as plain trends, in your units and against the range your lab gave, with no scores or traffic lights.
Squat, 3 x 5 at 100 kg.
Up from 97.5 kg two weeks ago.
Squat, working weight
kgProtocols
Phases, on your charts.
If you run a protocol, its phases show as shaded bands on your bloodwork, weight and lift charts, so a change in a marker can be read against what you were taking, and when.
Protocols stay hidden until you switch them on in Settings, and the coach sees only adherence, never individual doses.
Ferritin, ug/L
18 ug/LEsmero is not a medical device. It shows your numbers and says when to ask a professional.
Period tracking
Your period, read beside your training.
Log a period in a few taps or bring it in from Apple Health, and see it next to your lifts, weight and bloodwork. Your records stay on your phone.
Your bloods, dated by your cycle.
Lab draws taken while you track carry their cycle day, and the phase where it can be estimated, so a result from day 3 is not read against one from day 21.
Your pattern, not a rule.
After three cycles, Pattern shows your top sets, sleep and HRV in each phase against your own baseline. On average phase makes little difference to strength. This shows whether it does for you.
A heavier morning, explained.
Weigh-ins from three days before your period to day two say "Around your period: likely water".
On the pill, a hormonal IUD, in perimenopause or on other hormones, Esmero changes what it predicts, and hides phases when it cannot estimate them.
How period tracking works
Between sets, a plain answer.
Coach
Preview, then apply.
The coach reads your own history, builds and moves your plan as a preview, and logs what you tell it.
- Squats felt heavy all week and I slept badly. Should I change Thursday?
- Your sleep scores dropped this week and squats felt heavier. I would suggest a lighter Thursday. Want to preview that change? Nothing is applied until you tap Apply.

Say it, and it is logged
One sentence, logged.
Type it or say it. Sets, bodyweight, food, daily scores and skipped workouts save as soon as the coach reads them, with Undo on the card.

First light, before the first set.
What leaves your phone
Your records stay on your phone.
Workouts, labs, check-ins and photos are stored on the device, and the few things that leave do so only when you ask.
It settles here.
Workouts, labs, check-ins and photos are saved in a database on your phone and are not copied to a server of ours. Photos and lab reports are redacted on the phone before they are stored.
A coach message travels.
When you ask the coach, your message and the history it needs go from your phone, through our server, to the AI service that runs the Esmero Coach. Our server passes them through and does not keep them. This happens only after you answer the consent screen.
What leaves, and when.
Each thing that leaves, and what has to happen first.
- Exercise names, thumbnails and clips
- Fetched from ymove through our server when you browse the library. The request carries nothing of yours.
- Coach messages, and the history the coach reads
- Sent through our server to the AI service that runs the Esmero Coach, only after you answer the consent screen. On the consent screen, Allow includes bloodwork, blood pressure, protocols and cycle data, and Customise lets you leave any of them out. You can switch each one off later in Settings.
- What the coach remembers
- Facts you tell the coach, like a sore knee or a busy fortnight, are saved on your phone and go with your coach messages. Settings → Coach memory lists each one, to edit or delete, and backups include them.
- Your cycle
- Periods, symptoms, phases and factors are read by the coach only with the Cycle switch on. Allow on the consent screen turns it on, and you can switch it off in Settings. Cycle reminders can leave cycle words out of the notification.
- Attachments you send to the coach
- Only the redacted copy, only when you add it to a message. Originals never leave the phone.
- Exports and backups
- Only when you export, or switch on a weekly backup to your own Files or iCloud Drive folder. Bloodwork, protocols, cycle data and other sensitive records stay out unless you include them.
- Questions to the coach's reference library
- The question text only, never your records. The app works fully without it.
- A usage count
- Our server keeps a monthly count of coach usage for this build, the tokens and their cost, and one line per request with its size, timing and status, to apply fair limits. It never keeps what a message says.
- Your account and subscription
- Not yet. There is no account, so nothing of yours is held for one. Accounts and subscriptions come before launch, and this page will say what they keep.
- Food searches and barcodes
- The words you search for go to ymove through our server, and so does a scanned barcode that is not already on your phone. Nothing else of yours goes with them.
- A meal description or photo
- Sent to ymove only when you ask it to log a meal. In the works.
- A video of a set, for form checking
- Sent to ymove only when you tap Analyse. Deleted after analysis by default, never backed up, never sent to the coach. In the works.
Everything else stays.
We say when something is sent, and to whom. What the AI service that runs the Esmero Coach does with a message once it arrives is covered by its own terms.
Your accent and themes
Your colour, not ours.
Esmero has no brand colour inside the app, so pick the accent you like and it runs through the whole thing, this page included.
Accent
Actions stay black and white. Colour is kept for your data, for done, and for the accent you chose.
Five styles, light and dark.
- Future Pro
- Graphite
- Sand
- Forest
- Mono
Each follows the system setting or your own, with an ambient wash you can turn off.
Everything it tracks
Everything, in one calm place.
