This is really cool - I recently worked on a tool that I installed on my iPhone, which extracts all health data nightly to CSV and then to a cloud database. This was quite straightforward once you understand the permissions. I wonder why the OP didn’t do this and was instead using a simple health export CSV? The main concern I had with releasing this or turning it into a tool was data security. I have been swimming 1…

Earlier quoted context omitted.

I thought this was sort of deliberate for Apple Health. People use it to track sensitive information, like reproductive and mental health data, that should only be exported very intentionally.

Agreed. I'm fine jumping through a couple hoops to get my own data in this case.

Why would a malicious actor not be willing to setup the same infra as you, with an app on the iOS store to mine data once consented? I don’t see how api usage difficulty is a real security feature…

This is awesome! I’ve been working on and off for the last few months on an AI running coach app. Would love to compare notes of effectively prompting Claude or O3 to analyze workouts / build workout plans. In my experience it still requires a lot of hand holding (sudden mileage increases w/w, inconsistent intervals, etc)

Hey - if you're interested in prototyping with real data, we've built a platform for stuff like this -- Fulcra Context (https://www.fulcradynamics.com/). We have an iOS app that collects Apple Health data, and you can then share it with a coach/trainer/doctor/etc.

We have a REST API with python client lib (https://fulcradynamics.github.io/developer-docs/), an MCP server (https://fulcradynamics.github.io/developer-docs/mcp-server/), and did some experiments with ChatGPT actions as well (https://www.fulcradynamics.com/chatgpt).

It doesn't have the simplicity of a plain export to duckdb/sqlite, but it definitely helps solve a lot of the sharing/collaboration problems.

I am once again wishing screen time data was in Apple Health :( Exporting that is even worse.

I agree entirely. It's especially frustrating since the DeviceActivity framework comes close, but doesn't provide enough detail for users to allow apps to track this info.

The best approach we've found to tracking specific app use time is to have our app publish App Intents, and then tell users to trigger those intents with shortcuts. It's fairly effective, but very clunky to set up and has to be done app by app..

One could pretty easily wrap an MCP server around the ScreenTime activity SQLite database file on MacOS. You could use DuckDB like this server does.

I’ve found good value in making purpose-build MCP servers like that with the general model: DataDuckDBMCPLLM With verbose description for the LLM of an “sql” tool endpoint for it to use to explore.
