Getting Started with Metrya: Setup and FAQ

No. There is no sign-up, no email and no password. Metrya reads Apple Health on your iPhone and keeps its results on the phone.

No. Scores such as Recovery, Reserve, Sentinel, sleep debt and the Stress Monitor are calculated on your iPhone. Metrya has no server that receives health data.

If you choose a cloud AI model with your own API key, the data for that question goes directly from your phone to the provider you picked. Before the first request to a new provider, Metrya shows you the exact data it will send. More on the privacy page.

No, but it helps a lot. Without a watch, Metrya can still use steps, workouts, weight and sleep from other apps or devices. HRV, resting heart rate, sleep stages and wrist temperature come from a watch or another wearable that writes to Apple Health, such as Oura, Ultrahuman, Garmin or Whoop.

Free: Recovery, Sleep, Reserve, the Stress Monitor, Sentinel and Recovery debt, training, nutrition with barcode scan, Stack, Your week, the Body report and blood pressure.

Pro adds the AI Advisor, Metrya for Mac, PDF reports, planners and longer history, Pace of aging, Longevity Signals and the VO₂max trend, Body Vision and Stack patterns.

Pro is $14.99 a year or $4.99 a month, both with a 3-day free trial, or $19.99 once to keep it. Every plan unlocks the same Pro. You can cancel a plan any time in your Apple ID settings. Why a one-time option?

You choose. Apple Intelligence on supported iPhones, a model you download and run on the iPhone (Qwen, Gemma or Bonsai), or your own API key for Anthropic, OpenAI or Google. The first two send nothing anywhere. With your own key, you pay the provider directly and Metrya adds no markup. See how BYOK works.

Most Metrya scores compare you with your own baseline, not with other people. That needs history. Until there is enough, the app says what it is waiting for instead of guessing.

Yes, if the device writes its data to Apple Health. Metrya reads Apple Health, not the device's own cloud. What you get depends on what the device shares with Health.

The daily dashboard works on the last 30 days, which keeps it fast. Some screens read further back when they need it: charts can show months as weekly or monthly summaries, and Recovery debt looks back up to a year to find past runs.

Yes. Choose the language in Settings → Display → Language. Translation is gradual, and the Language screen lists which screens are translated so far.

Reports export as Markdown through the share sheet, and there is a data export in Settings. Files are written on the phone. Nothing is uploaded.

Four models, all Apache-2.0. Metrya checks each file before first use. Qwen is the one we recommend. Gemma and Bonsai are alternatives.

• Qwen 3.5 2B — 1.2 GB download. iPhone 13 Pro or newer with 6 GB of memory. 8K of context. The balanced one.
• Qwen 3.5 4B — 2.6 GB. iPhone 15 Pro or newer with 8 GB. 16K of context. The best answers of the four, and the slowest.
• Gemma 4 E2B — 2.4 GB. iPhone 15 Pro or newer with 8 GB. 8K of context. Google's model. It can read a meal photo.
• Bonsai 8B — 1.1 GB. iPhone 13 Pro or newer with 6 GB. 4K of context. The smallest download. Text only.

Reading meal photos adds about 640 MB on Qwen and about 940 MB on Gemma, and needs 8 GB of memory. On a 6 GB iPhone the text model still works; the photo part is just not offered.

Metrya checks your iPhone's memory and only offers models it can hold. You see the free space before you start. The download continues in the background and resumes if it stops. Models are kept out of your iCloud backup, and deleting one frees all of its space. Find them in Settings → AI Model → On-device models.

There are three, and we would rather you hear them here.

It is slower. A full answer can take tens of seconds. A cloud model takes a few. It is heavy. While the chat is open, the model uses several gigabytes of memory and the phone gets warm. It unloads when you leave the chat. It is a beta.

So use it for the longer questions, like a week of nights, a training block, or something you would rather not send anywhere. For a quick "how did I sleep?", Apple Intelligence answers in seconds.

One more limit: iOS does not let a background task load a model this large. So with a downloaded model, a scheduled report's notification still arrives on time, but the report is written when you tap it. With your own cloud key, reports are written in the background.

It used to be. A year ago you had to pick a file format, find the model, install a separate app to run it, and hope your phone had enough memory.

In Metrya it is four taps: Settings → AI Model → On-device models → Download. Metrya hides the models your iPhone cannot hold. The download resumes on its own, and the file is checked before first use. The model then sits in the same list as Claude and GPT, and you pick it the same way. There is no setup, no account and nothing to top up. The only choice is whether you will wait a bit longer for an answer that never leaves your phone.

Yes, with Pro. The weekly report covers your last full week in three pages: sleep, recovery, training, movement, food, supplements and habits. Choose who it is for — Me, My coach or Sleep only — and it keeps only those sections.

There are also PDFs for a week of workouts (every session drawn out, with zones, splits and heart rate recovery), HRV (90 nights), Heart rate (90 days), VO₂max (12 months, with how you compare for your age and sex), Body and BMI (12 months), Blood pressure (90 days) and your Timeline, which lists every entry. The same week can also be saved as CSV, JSON or Markdown files.

Find them in Reports under PDF reports, or tap the document button on the VO₂max, HRV, heart rate, BMI, Body report, Blood pressure and Timeline screens and on the Train tab. Every PDF is made on your iPhone and handed to the share sheet. Nothing is uploaded. Paper size follows your region (A4, or US Letter in the US and Canada). Every page says it is a wellness summary, not a medical record. Open a sample of each report.

Reports are made on your iPhone. The Weekly Readout looks at the week that just ended. It gives three scores — Night, Recovery and Output — each against the three weeks before. Under each score, your metrics are sorted into gaining ground and slipping, and every row opens to show where the number came from. Output counts steps, active energy, workout load and time in daylight, each against your own last 60 days. If you don't measure one of them, the others share its weight.

The Body Report turns your scale readings into a body-composition trend and the pace you have actually kept. BMI never shows alone: waist-to-height, body fat % and FFMI sit next to it, each with its own ranges.

Free shows every chart and number, and 90 days of trend. Pro adds a short AI summary with one thing to try, longer history with your projected pace, the what-if and target body-fat planners, and the PDF and Markdown exports.

Because a report from two days of data is worse than no report. A weekly score needs at least four days of data. The body-composition trend needs at least eight weight readings over about a month.

Until then you see progress, not a lock — for example "6 of 8 readings — the trend needs two more" — so you know what is missing. You never see a paywall for data you don't have yet: Metrya checks the data before it checks Pro. If a metric is missing completely, it is left out, and one line at the bottom says what would bring it in.

Metrya reads the HRV samples your Apple Watch already records and turns them into a 0–100 stress estimate, scored against your own range, not a population average. It is worked out on your iPhone, with no AI involved.

It is not a mood meter, it is not continuous, and it is not a diagnosis. Your watch measures HRV at irregular times, so each reading shows when it was taken and how sure it is, and the chart leaves gaps where there was no reading. You get Day, 7-day and 30-day views, a short 4·4·6 breathing session, and optional alerts with quiet hours and a daily limit. They stay off until you turn them on.

HRV status compares the average of your last 7 nights of sleeping HRV with your own normal range from the 60 nights before. It says Balanced, Unbalanced or Low. The first status needs about 4 weeks of wearing your watch to bed.

High HRV is not always good news. If your HRV is above your range while your resting heart rate, breathing rate or wrist temperature is also up, Metrya says why it is not calling it good, and Recovery is held: high HRV cannot lift your score above what a normal HRV would give. It only stops a rise. It never pushes the score down. The status and the held line are free; the range chart and the checks behind it are Pro.

Training turns each workout from Apple Health into a heart-rate curve you can scrub, with estimated zones and time in each zone. Where there is GPS, you get a route map and splits per kilometre. You also see training load and how your next night compared with your 30-day baseline. The hub shows your week's load against your usual week, the split between easy, moderate and hard, and a 28-day grid. A button at the bottom loads one more month of older workouts each time you tap it.

Sleep shows each night with a score, a large chart of your sleep stages, and each stage against your own 30-night range. Above that: last night, your sleep debt, and how regular your bedtimes were over 28 nights. Nights recorded without a watch keep everything that only needs a start and an end time, and the screen says which parts a watch would add. Nothing is guessed to fill a gap.

No. Stack is a list of what you already take. Pick from a catalog of 150 supplements stored on your phone, or add your own, with the dose, time of day and start date. You tick each one off in Today, and a skip asks for a reason. Reminders are optional and off until you turn them on. There are no streaks and no scores.

Each item says whether its effect could even show up in your data — some act within hours, others over weeks. With Pro, Stack shows how your sleep, HRV and other numbers looked on days you took it, on days you skipped it, and since you started. A difference is only called a pattern when it is bigger than your normal day-to-day changes. These are patterns in your own data, not proof. Stack is not advice, and your list never leaves the phone.

Metrya keeps every reading your cuff writes to Apple Health, and every one you type in, with its date, time of day and source. Systolic and diastolic always appear together, with the scale.

The trend shows morning readings only, one per day, by default. Readings later in the day are often a few mmHg higher, so a mixed chart can show a slope that is really just the time of day. Tap a reading to see what was around it — last night's sleep, yesterday's sodium and alcohol, a workout that ended shortly before, your Reserve that morning — plus pulse pressure and mean arterial pressure. Nothing is called a cause, and differences under 3 mmHg are treated as normal cuff noise. Free shows 90 days; Pro shows a year.

Three Pro metrics: Autonomic Age from your HRV against people of your age and sex, Fitness Age from measured or estimated VO₂max, and Sleep Longevity Risk from how long and how well you sleep. They are worked out on your iPhone from Apple Health data and don't need an AI model.

VO₂max has its own screen. The reading, its source and its category are free. The trend, the comparison with your age and sex, the next milestone and fitness age are Pro. Read the Longevity Signals guide.

Add a goal photo — or describe your goal, or pick a body-shape preset — and a current photo. The AI reads both next to your scale, sleep and training data. You get a body-composition starting point, a realistic timeline, and a suggested plan for training, food and recovery. Weekly check-in photos track your progress, and the Advisor keeps your goal in mind when you ask it something.

Yes. The iPhone keeps your history and the Advisor; the Watch shows "now". It has a live Reserve gauge that keeps updating from the Watch's own readings, last night's sleep with overnight HRV, resting heart rate and wrist temperature against your 30-day baseline, nutrition targets, caffeine on board, a cold-plunge timer, and Heads Up for air quality and pollen. Watch-face complications for Reserve, Recovery and heart rate need Pro.

The Watch talks only to your iPhone, plus one weather lookup with a rough location for Heads Up. No health data goes with it. See Metrya on Apple Watch.

Yes. Metrya for Mac is included with Metrya Pro on your iPhone. It is not a second subscription. It is an experimental beta (version 0.2.7). It needs macOS 26 or later and Metrya 2.11.21 or later on the iPhone.

The Mac keeps a year of your data. It shows your week on one map against your usual, and has pages for Training, VO₂max, BMI, Sleep and Nutrition. Lab compares days with one change you already log — a Stack item, a tag or a workout — against days without it, for one number. Routines answer a saved question on a schedule and only show a report when something changed. You can ask with Apple Intelligence, a local model in Ollama, or your own key.

It is not on the Mac App Store. Download Metrya.dmg from the Mac page and drag it into Applications.

Open Metrya on the Mac. It shows a six-digit code. On the iPhone, go to Settings → Mac, pick your Mac and type the code. Then tap Send everything once; after that, Keep in sync or Send changes keeps the Mac up to date. Both devices must be on the same Wi-Fi when you send.

The data goes from your iPhone to your Mac over your Wi-Fi, encrypted with the pairing code. There is no Metrya server in between and no account. Without the code, the connection is refused. A send only reads: it changes nothing on your phone. Anything you turned off for the AI on the iPhone stays off on the Mac. If you pick a cloud model on the Mac, the question goes to that provider on your own key, and the Mac shows you the text before the first send. How iPhone, Watch and Mac work together.
