How to set up Apple Watch for Type 2 Diabetes: what Sam tracks - and what your blood glucose monitor handles
How to set up Sam if you have Type 2 Diabetes, which metrics matter, and how to prepare a report for your next diabetes clinic appointment.
On this page
If you wear an Apple Watch and live with Type 2 Diabetes, Sam shows you the daily context alongside your existing blood glucose meter: resting heart rate, sleep, and activity - separate from your glucose readings. This guide explains how the two work together.
Two separate tools
Your blood glucose meter or CGM system remains your central tool for glucose readings - independent of whatever else you use. The article Can Apple Watch measure blood glucose? explains why no wearable can currently handle this task.
Sam is a separate tool: it reads resting heart rate, sleep, and activity from Apple Health - signals linked to insulin sensitivity, but not glucose values themselves.
Setup in a few steps
- Wear your watch regularly. Resting heart rate is calculated automatically in the background.
- Enable sleep tracking so Sam can include your sleep data.
- Connect Sam to Apple Health and grant permission for resting heart rate, sleep, and activity data.
If your glucose meter or CGM already syncs to Apple Health, those readings stay visible in the Health app - but Sam itself does not read or analyse them.
The report for your diabetes appointment
Sam summarises your resting heart rate, sleep, and activity trends monthly in a PDF report. Combined with your glucose logs, this gives a fuller picture: the numbers from your meter, the daily context from Sam.
Where Sam Health fits in
Sam reads resting heart rate, sleep, and activity from Apple Health, compares them against your personal baseline, and summarises them monthly in a report. For movement and sleep strategies recommended by current diabetes guidelines, see the article Living with Type 2 Diabetes: movement and sleep.

Frequently Asked Questions
Does Sam replace my blood glucose meter or CGM?+
No. Sam does not read blood glucose data and does not replace your meter or CGM system. Both continue to work independently - your meter for glucose values, Sam for resting heart rate, sleep, and activity.
Do I need an Apple Watch, or will any wearable work?+
You do not need an Apple Watch. Sam reads Apple Health and works with any wearable that syncs there - Oura, Whoop, or Garmin, for example. You do need an iPhone.
How do I prepare a report for my diabetes appointment?+
Sam generates a monthly PDF report summarising your resting heart rate, sleep, and activity trends. Bring this alongside your blood glucose logs - it shows the daily context that glucose numbers alone do not capture.
Can I still enter my blood glucose values in Apple Health?+
Yes. Many glucose meters and CGM apps sync automatically to Apple Health, so your readings appear alongside your other health data. Sam itself does not read these values, and they do not factor into Sam's analysis.
Can I connect my Freestyle Libre or Dexcom sensor to Apple Health and Sam?+
You connect your CGM sensor directly to Apple Health, not to Sam. The Dexcom app offers official Apple Health syncing, so your readings appear there with your other health metrics. The LibreLink app from Freestyle Libre does not currently sync directly to Apple Health - only unofficial third-party tools do. Either way, Sam does not read glucose values and does not include them in its analysis - Sam stays focused on resting heart rate, sleep, and activity.
Which wearable works best with Type 2 Diabetes - Apple Watch, Oura, or Whoop?+
There is no single wearable that is universally best for Type 2 Diabetes. What matters is whether it reliably sends resting heart rate, sleep, and activity to Apple Health, since those are the metrics Sam can use. Apple Watch, Oura, and Whoop all do this; which device suits you best depends on comfort, battery life, and cost - not on diabetes-specific differences.
