Connect the AI Agent you already use.
Somvia gives your account a private remote MCP endpoint. Your Agent reads the scores, the daily values and the session detail, and answers from your own numbers. You choose the model, so you can use the strongest one you have, and it only changes when you change it. No export, no desktop server.

Built to stay private
- Health access
- iOS controls which health data Somvia can read. Your upload selections separately control which categories are shared with connected Agents
- Upload
- Health data upload is off by default. Enable it in Connection to share selected categories with your Agents. Local scores and analysis work without uploading health data
- Where the scores are computed
- On your iPhone, from the data already in Apple Health. No model is asked to guess them.
- Transport
- Encrypted in transit. Your private MCP connection is bound to Sign in with Apple.
- Tokens
- Access tokens are stored server-side only as SHA‑256 hashes, never in plain text.
- Ads & resale
- No ads. Your data is never sold.
- Deletion
- Delete the data on the server from the Connection page and keep your account, or delete the account and everything with it from Settings, any time.
Questions
Where do the scores come from?
From the data your devices have already written to Apple Health: overnight sleep and heart rate, resting heart rate, HRV, and the workouts themselves. Somvia estimates the scores on your iPhone using published sport-science models, and every score opens to show which measurements it came from.
Do I need an Apple Watch?
Apple Watch worn during sleep provides the overnight readings used for recovery and HRV analysis. Somvia can also read records from other devices through Apple Health, but available scores and workout details depend on which data those devices write.
How long before the scores appear?
Each analysis needs different records. Sleep uses recorded nights, recovery needs enough overnight readings to compare with your usual, and HRV status compares your recent nights with a longer history. Existing Apple Health records count, so you do not have to start from zero. The app shows which data is missing.
How does Somvia connect to an AI Agent?
Somvia gives your account a private remote MCP endpoint. Claude, ChatGPT, Codex and other OAuth-capable clients sign in with Apple. OpenClaw, Hermes, Grok, Muse and other Agents that connect with a key use a private som_ access token issued in the app. The Agent reads your scores, daily values and session detail through the standard MCP connection.
Which AI model does Somvia use?
None of its own, so the choice is yours. When you ask about your training, the agent you connect, such as Claude, ChatGPT, OpenClaw or Hermes, answers with the model you selected in it, and you can switch to a stronger model as soon as one is available. An app with its own AI picks the model for you. With Somvia you know which model reads your data, and it only changes when you change it. The scores themselves are calculated on the iPhone with published formulas, and Somvia's server does not call a language model. Somvia has no AI allowance or credits, so how much you ask depends only on your own AI plan.
What is MCP?
MCP (Model Context Protocol) is an open standard for connecting compatible clients to external tools and data sources. Somvia exposes your scores and health data as a standard remote MCP server, with no custom integration required.
Does the memory follow me between Agents?
Yes. Goals, injuries, medication and preferences are stored with your account rather than inside one client, so an Agent you connect later reads what you told the previous one. Every entry can be read, edited and deleted in the app.
Does Somvia provide medical advice?
No. Somvia is not a medical device and does not provide medical advice, diagnosis, or treatment. The scores are estimates, not clinical measurements. Always consult a qualified healthcare professional in addition to using Somvia and before making any medical decisions. For general background, see Apple Health data, NIH sleep information, and CDC physical activity information.
Is my health data private?
Scores and training analysis run on your iPhone. Health data upload is off by default. If you enable it, selected data is sent over an encrypted connection to Somvia's server for your connected Agents to read. You can change the shared categories, revoke connections, delete server data or delete your account. No ads and no sale of your data.
How much does Somvia cost?
The app is free to install and set up. Somvia Pro (a subscription or a one-time lifetime purchase) unlocks the scores, hosted sync and agent access. Current pricing is shown in the app.
