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
Ask anything in plain English. "Why am I tired?" or "Is my HRV trending down?" — get data-grounded answers, not generic tips.
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.
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.
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.
How AI billing works

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.

Traditional health AI apps
Pay monthly for AI you don't control
  • $10–30/month subscription, billed whether you open the app or not
  • Your data routed through the app provider's servers
  • Heavy markup — actual AI cost is fractions of a cent per query
  • Lose everything the moment you stop paying
Metrya
Bring Your Own Key — zero markup, full control
  • Core features are free, forever — Apple Health analysis, AI chat, dashboard
  • Your API key connects directly to Anthropic / OpenAI / Google — no middleman
  • Zero markup — you see every cent, you stay in control
  • Optional Pro upgrade ($9.99 once, lifetime) adds your own data for richer AI context
Pro is optional — it enriches context, not access The free tier already lets your AI model analyse all your Apple Health data. Pro lets you layer in your own context — session logs, check-ins, supplements, equipment, and food habits — so the AI's answers go deeper. It also unlocks Recurring Insights: scheduled daily, weekly, or monthly AI reports delivered automatically. One payment, lifetime access, all future features included.
Real-world cost: a $5 top-up typically lasts months of daily use Each conversation costs a fraction of a cent. Most users top up once and forget about it — you're genuinely paying for what you use, nothing more. No surprise charges, no monthly billing.

FAQ

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?
Metrya supports Anthropic Claude, OpenAI, and Google Gemini. You'll need an API key from at least one of these providers. 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.
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.
