A coach that knows your numbers
Ask about your sleep, water, training or supplements in English, German or Hungarian. It answers from your own data, offers the next question, and opens the right screen when you want to act. On the watch, by voice.
Android + Wear OS beta
iPhone + Apple Watch, coming soon
Your health app collects. Carpemind makes it act.
Carpemind plugs into the health store your phone already has, links your sleep, heart rate and training with what you log, and turns it into one small step on your phone or your wrist. Its AI works on the phone first.
Free during the beta, everything included. Nothing to migrate. A wellness app, not a medical device.

A layer, not another silo
Plug in. Don’t switch.
Most trackers want to become your new dashboard. Carpemind goes the other way: it reads and writes the health store your phone already has, so your history, your scale and your other apps stay exactly where they are.
Your apps keep working
Google Health, Samsung Health, your scale’s app and your food app keep their place. Each entry is checked before writing, so nothing is counted twice.
Phone and watch, one app
Plan on the phone, run it on the watch. Every watch flow works with no phone nearby and syncs once, in order, when they meet again.
Same idea on every platform
Health Connect and Wear OS today. Apple Health and Apple Watch are next, built the same way, so switching phones doesn’t mean starting over.

AI on the phone first
Smart about your health. Quiet about it.
Where your phone has a built-in model, Carpemind’s AI runs on it, so what you ask and what it reads stay on the phone while it writes. Cloud AI for deeper analysis is on the way, as an option you turn on. Say no, and everything else works the same.
1 · You ask
“How did I sleep this week?”
Typed, or spoken to the watch.
2 · Filtered on the phone
Personal details stopped
Card and bank numbers, contact details, ID numbers and birth dates are caught by fixed rules before any model sees the text.
3 · On-device model
Gemini Nano or Apple Intelligence
The answer is built from your numbers by rules, then put into words by the model on your phone.
4 · Checked, then shown
Labelled, every time
The text passes the same safety checks as the template, or the template shows. Model text says “Written by on-device AI”.
On-device AI
Your phone’s own model
Used first wherever the phone has one that apps can use. Recent Pixel and Galaxy phones and many others do. Which phones?
Cloud AI · opt-in · coming
Deeper analysis, if you want it
A larger model for longer reasoning across your weeks of data, run in the EU, and the AI for phones without their own model. Off until you turn it on under Profile → Privacy and data.
Fixed rules
No AI where it matters most
The stress and mood estimate, your water goal, readiness and the morning briefing come from fixed, explainable rules. Tap “Why?” to see them.
- Your notes are never sent to a cloud model. Not with Cloud AI on, either.
- You always see which AI answered. A pill on the chat and a label under every model text, kept in your export.
- Consent for each use. On-device AI, Cloud AI and insights each have their own switch, off until you turn them on.
- No profiling for anyone else. No ads, no data sold.
Gets better without asking for more of your data
The on-device models improve with your phone’s own system updates. Carpemind’s side, the rules, safety checks and the knowledge base with its sources, grows with every release. Neither needs your entries to leave the phone.
What it does today
Senses. Understands. Acts.
It reads the signals you already collect, works out what they mean for today, and puts the next step where you’ll see it. You decide; it never acts for you.
Training that progresses
A goal wizard drafts a program. After each workout the next targets update by double progression, with the reason shown.
Body, in context
Weight, body fat, muscle, visceral fat and waist, each against a usual range with its named source.
Calm you can feel
Breathing paced by soft taps on the wrist, or calm music with its beat on the watch. Offered when your heart rate points to stress.
A morning briefing
Last night and yesterday in two lines, with “Why?” behind every point. Sauna, supplements and effort after training feed it too.
Water that follows your day
One tap logs 250 ml on the watch, tile or complication. The goal rises on active days.
Food, with the app you already use
Search the catalog, compose meals, save your own foods. Meals from MyFitnessPal, Cronometer or Lose It! arrive through Health Connect.

Routines, your exercise list and today’s goals are stored on the watch. Big targets, one job per screen. These are screenshots of the Wear OS app in the beta.

What you have today, and what Carpemind adds
Google and Apple built the health store. Carpemind builds on top.
Health Connect and Apple Health are excellent at keeping your data in one place and sharing it with the apps you allow. Acting on it, from the wrist, is the part we fill.

Your meals, your choice
Keep your food app. Share only what you want.
Carpemind reads meals from the health store, whichever app logged them, and shows each with its source. Whether your Carpemind meals go back to the store is a switch, off until you turn it on.
- Catalog search and meal composer · calories, protein, carbs and fat add up as you go
- Meals from other apps · shown with their source, never counted twice
- Next: photo estimates and barcodes · on the device where it can
- Next: re-log a saved meal from the watch

With it on, apps that read nutrition from the store, such as Google Health, Samsung Health and Lose It!, show them. Most food apps, MyFitnessPal and Yazio included, only write to the store, so they won’t.
The science of felt rhythm
Why vibration on the wrist?
Carpemind pairs slow breathing and calm music with a soft rhythm you can feel. What research says about it, the strong parts and the weak ones.
Slow breathing does the heavy lifting
About six breaths a minute is the best-studied part: many studies link it to a calmer heart rhythm and feeling more relaxed. The session paces 4 s in, 6 s out, with a tap at each turn.
A rhythm, not a constant buzz
On its own, vibration has not been shown to calm, and a steady buzz may even be slightly stimulating. So Carpemind’s taps follow your breath or the music, then pause.
Honest about the limits
Studies on felt sound are small and mixed, effects are modest, and Carpemind itself has not been tested in a study. No “miracle frequencies”. It is made for relaxing.
See the research and sources
The studies are research background, not tests of Carpemind.

Your data
Health data, handled like health data.
You choose what Carpemind can touch, and every choice can be changed later in the app under Profile → Privacy and data.
Consent for each purpose
Your entries are health data, so Carpemind asks for your explicit consent (GDPR Art. 9). Every optional feature stays off until you turn it on.
Permission per data type
Health Connect asks for each type, read and write separately. Your phone reads it; turn any type off and Carpemind keeps working with the rest.
Stored in the EU
Your account and synced entries live on Carpemind’s server at Hetzner in the EU. Your phone and watch keep a copy, so they work offline.
Encrypted on the way
Every connection is HTTPS. Sign-in tokens sit in the phone’s secure storage, and your pictures and videos open only through short-lived links.
AI on the device first
Where your phone can, AI runs on the phone. Cloud AI only runs if you turn it on, and never sees your notes. Stress and mood come from fixed rules.
Yours to take or delete
Download everything or delete your account from the app at any time. No ads, no selling, no profiling for others.
Read the privacy notice
Carpemind is a wellness app, not a medical device. Nothing it shows is a diagnosis.
Questions
Before you install
Do I have to stop using my current health app?
No. Keep it. Carpemind writes into Google Health Connect, which your current apps already read from. Think of it as a faster keyboard and a coach for the health data you already keep.
Will my entries show up twice?
No. Your phone reads Health Connect, compares it with what Carpemind has, and writes only the entries that are missing.
Does the watch need my phone nearby?
Only to sync. Logging and full workout routines run on the watch alone, and entries wait in a queue until the phone is back in range. The voice coach needs the phone, since that is where the AI runs.
Does my data stay on my phone?
Your phone reads the health store and keeps a copy for offline use. What Carpemind syncs, your account and entries, is stored on our server in the EU, so your phone and watch agree and you can export it. When the AI writes, it does so on your phone if it can; Cloud AI only runs if you turn it on, and your notes are never sent to it.
When is the iPhone and Apple Watch version coming?
It is in development, built on Apple Health in the same way the Android app is built on Health Connect. We will announce the date here.
I log food in Yazio. Do I have to switch?
No. On iPhone, Yazio shares meals with Apple Health, and Carpemind will read them from there. On Android, Yazio doesn’t share meals with Health Connect yet, so they can’t reach Carpemind. MyFitnessPal, Cronometer, Lose It! and Samsung Health do share. Use Carpemind’s own food logging only if you want to.
Which phones run the AI on the phone itself?
Carpemind uses the model built into the phone, so your data stays on it while the AI writes. Not every phone has one that apps can use. Checked in October 2026:
- Google Pixel 9, 9 Pro, 9 Pro XL, 9 Pro Fold and newer (Gemini Nano)
- Samsung Galaxy S26, S26+, S26 Ultra, Z Fold7, Z Fold8, Z Flip8, Z TriFold
- OnePlus 13, 13s, 15, 15R · Xiaomi 14T Pro, 15, 15T, 15 Ultra, 17, 17 Ultra · OPPO Find X8, Find X9, Find N5 · vivo X200, X300 · Honor Magic 7, Magic 8 Pro · Motorola Razr 60 Ultra · Sony Xperia 1 VIII
- iPhone 15 Pro, 15 Pro Max, 16 and newer, iPhone Air, with Apple Intelligence turned on (when the iPhone app is out; Apple Intelligence doesn’t speak Hungarian yet)
The Galaxy S25 and older Galaxy phones have Galaxy AI, but not the Gemini Nano version other apps can use. On those, and on every other phone, Carpemind’s AI features stay off for now, and will use Cloud AI once it arrives, if you turn it on. Everything else works the same. The app tells you which applies to your phone under Profile → Privacy and data.
Which watches work?
Wear OS watches running Wear OS 4 or newer, such as Pixel Watch and Galaxy Watch. Apple Watch support comes with the iOS release.
