What file should I give the AI?
The JSON export works well because it's structured and complete. You can also paste in a CSV.
How to analyze Apple Watch workout data with AI
Large language models are good at reading structured data. Export a workout as JSON and you can ask ChatGPT or Claude to analyze it like a coach.
The idea
An LLM can't read Apple Health directly — but it can read a file you give it. Workout Exporter produces a complete, structured JSON export of a workout: heart rate, route, splits, and summary statistics. Hand that file to ChatGPT or Claude and ask questions.
Good questions to ask
- "Was this an aerobic or threshold effort based on the heart-rate data?"
- "Did my heart rate drift upward in the second half? What might that indicate?"
- "Summarize this workout and suggest what to focus on next session."
- "Compare these two workout files and tell me which was harder."
Your data stays under your control
Workout Exporter never sends your data to any AI service. The JSON file is generated on your iPhone; you decide whether to upload it to an assistant, and to which one. Nothing happens automatically.
Step by step
You control what you share. The app sends nothing to an AI service on its own.
1
Export the workout as JSON
In Workout Exporter, open a workout, tap Export, and choose JSON (full raw data).
2
Save the file
Save it to Files, or AirDrop it to your Mac.
3
Open ChatGPT or Claude
Start a chat and attach the JSON file.
4
Ask your question
Ask for a summary, an effort assessment, or a comparison — then iterate.
Frequently asked questions
Does the app send my data to ChatGPT automatically?
No. Export is on device; uploading to an assistant is a manual choice you make.
Will the AI be accurate?
Treat AI output as a helpful second opinion, not medical or coaching advice. It reads the numbers you provide.
