Everything your health data
has been trying to tell you

Metrya connects to Apple HealthKit and gives you an AI advisor that actually knows your numbers.

AI Health Advisor (Pro)
Ask anything in plain English. "Why am I tired?" or "Is my HRV trending down?" — get data-grounded answers, not generic tips. Pro also lets you turn any AI reply into actionable goals with one tap.
Live Health Dashboard
30 days of Apple Health data at a glance — sleep, HRV, resting heart rate, activity, body composition, and more.
Biological Age Score
See your estimated biological age, calculated from cardio fitness, HRV, sleep quality, and metabolic markers — with a full factor breakdown.
Anomaly Detection
Metrya learns your personal baselines for HRV, resting heart rate, SpO₂, sleep, and more — then alerts you when something meaningfully deviates. On-device, no AI key needed.
Recovery Score
A daily 0–100 score computed entirely on-device from HRV vs your baseline, resting HR, sleep duration, deep + REM quality, and HRV trend. Tap to see every contributing factor — no API key needed.
Personal Context (Pro)
Log supplements, fitness equipment, and dietary approach. The AI advisor uses your personal context to give tailored, specific recommendations.
Wellness Log (Pro)
Track sauna sessions, cold plunges, meditation, energy, mood, stress check-ins, and lifestyle events — then ask the AI how they affect your data.
Recurring Insights (Pro)
Schedule daily, weekly, or monthly AI health reports. Metrya automatically reviews your latest data and delivers a personalised written report — straight to your notifications.
Goals & Streaks — Free
Set health goals (steps, sleep, HRV, weight and more) and track them with daily streaks and milestone badges — no Pro required. In Pro, the AI can extract goals directly from chat advice with a single tap.
Bring Your Own Key
Use Claude, OpenAI, or Gemini with your own API key. No data ever touches our servers — processing goes directly from your phone to your chosen AI provider.

Step-by-step guide
3
Start asking
Open the AI Advisor and ask anything about your health. The AI reads your last 30 days of data to answer.

No subscriptions. No margins.
You pay the AI directly — or not at all.

Most health AI apps charge $10–30 a month, quietly pocketing the difference between what you pay and what AI actually costs. Metrya skips the middleman entirely — you connect your own account in minutes, no technical background needed.

1
Create a free AI account
Sign up at Anthropic, OpenAI, or Google — the same companies behind ChatGPT and Gemini. Free in under 2 minutes.
2
Get your personal access key
In their dashboard, generate an API key — think of it as a password that lets Metrya talk to the AI on your behalf. Copy and paste it once.
3
Add $5 of credit, done
Top up a small amount directly with the AI provider. No subscription — you're charged only for the questions you actually ask, at pennies each.

Common questions

Everything you need to know before downloading.

Does Metrya store my health data?
No. All your Apple Health data stays on your device. When you ask a question, only the relevant data window is sent directly from your phone to your chosen AI provider (Claude, OpenAI, or Gemini) using your own API key. Metrya has no servers and does not receive, store, or transmit your health data.
What API key do I need?
AI Advisor is a Pro feature. Once you've unlocked Pro, you'll need an API key from Anthropic Claude, OpenAI, or Google Gemini. API usage is billed directly by your chosen provider at their standard rates — Metrya doesn't add any markup or take a cut. Step-by-step guide for all three providers →
What Apple Health data does it use?
Metrya reads sleep (stages, duration), heart rate, HRV, resting heart rate, heart rate recovery, respiratory rate, SpO₂, step count, walking speed, body weight, BMI, body fat percentage, and lean body mass. It supports Apple Watch, Oura, Garmin, Withings, and any other HealthKit-connected device.
Is Pro a subscription?
No. Pro is a single non-consumable in-app purchase — you pay once and own it permanently. No recurring billing, no monthly fees. The price is set in App Store Connect and confirmed at checkout through Apple's standard payment flow.
What if I reinstall the app?
Your Pro purchase is tied to your Apple ID and can be restored at any time via Settings → Restore Purchase. Preview usage counters for free users are stored in iOS Keychain and survive reinstalls.
What are Recurring Insights?
Recurring Insights is a Pro feature that lets you set up automated AI health reports on a daily, weekly, or monthly schedule. You choose which data to include (sleep, HRV, activity, bio age, wellness logs), set a time, and Metrya generates a written report automatically whenever the app is opened after your scheduled time. Reports are saved in-app and a notification is sent when each one is ready.
What is Anomaly Detection?
Anomaly Detection builds a personal 30-day baseline for 8 key metrics — resting heart rate, HRV, SpO₂, body temperature, sleep duration, deep sleep percentage, step count, and respiratory rate. When today's reading falls meaningfully outside your own normal range, a dismissible alert appears on your dashboard. For significant deviations, a single notification is sent per day. Everything runs on-device — no AI key required, no data leaves your phone.
What is the Recovery Score?
The Recovery Score is a daily 0–100 readiness number computed entirely on your device — no AI key needed. It weighs five signals against your own 30-day rolling baseline: HRV (35%), resting heart rate (25%), sleep duration (20%), deep + REM sleep quality (10%), and 3-day HRV trend (10%). Missing components are excluded and the remaining weights are renormalized. Tap the card on your Dashboard to see the breakdown. Labels: Optimal (85–100), Good (70–84), Fair (40–69), Low (0–39).
Are Goals & Streaks free?
Yes — goals and streak tracking are completely free. You can create goals for any health metric (steps, sleep, HRV, weight, and more) or set free-form habit goals, and Metrya tracks your daily streaks, milestones, and best streaks automatically. The Pro-only feature is AI Goal Extraction: in any AI Advisor conversation, a single tap lets the AI read the message and propose specific, actionable goals based on the advice it just gave you.
Can I explore my exported health data?
Yes. In the app, go to Settings → Data and export your last 30 days of processed metrics and Biological Age as a JSON file. Then open the free Metrya data visualizer to load and explore that file in your browser.
Is the AI giving me medical advice?
No. Metrya is a data analysis and wellness tool, not a medical device. It helps you understand patterns in your own data. Always consult a qualified healthcare professional for medical decisions.
