How Do I See My Stelo Glucose Next to My Meals and Workouts?

HealthOS does not connect to Stelo directly. It reads Stelo data written to Apple Health or a Stelo/Dexcom Clarity CSV import, and places readings next to meals and workouts around them. The Apple Health route is delayed by about 3 hours.

HealthOS does not connect to Stelo directly. It only reads Stelo data written to Apple Health or a Stelo/Dexcom Clarity CSV import. The Apple Health route is delayed by about 3 hours, so same-day review is possible after that delay. HealthOS is not for urgent or current decisions.

HealthOS places each reading next to the meals and workouts around it.

Use the Apple Health route

If you already log meals and workouts in the app, this route is mostly passive. Confirm Stelo can write glucose to Apple Health, and confirm HealthOS can read glucose from Apple Health. Log meals and workouts with real times. Wait about 3 hours for the Apple Health route to show a reading.

For daily use, you do not need to export anything.

Import a CSV for historical data

Use this route for historical review or when Apple Health is not available. Export a CSV from Dexcom Clarity or Stelo, then import it in Settings under Import glucose from a file. The readings sit on the same timeline.

Both routes land on the same timeline.

Read the meal and workout patterns

On your timeline, you might see a lunch marker at 12:30 and a glucose rise after it. If you log a brisk walk after that meal, the line may be lower by the time you review. That is the pattern to watch for.

A single rise above 140 mg/dL is not a diagnosis. In observational data reported by Spartano et al. 2024, adults without diabetes in the Framingham study spent about 3 hours a day above 140 mg/dL. That is observational context, not a diagnostic cutoff or target.

Troubleshoot missing glucose

Check three things: - Confirm Stelo can write glucose to Apple Health. - Confirm HealthOS can read glucose from Apple Health. - If you wear a FreeStyle Libre, SiBionics, or Syai sensor, their apps do not write glucose to Apple Health. Export the file from that maker's app and import it in Settings instead.

Dexcom G7, Stelo, and Lingo also write to Apple Health. The Apple Health lag is about 3 hours for each.

The timeline is a wellness view, not a medical device, and not for dosing insulin.

Want to see it in your own numbers? Drop a Dexcom Clarity or Stelo export into the free CGM report for a browser-based AGP, time in range and biggest rises. If you don't have a sensor, learn about HealthOS Sensor.
