Keep supported entries connected to Apple Health
The current Glucose App Store listing states that the app integrates with HealthKit by writing inputted entries to the Apple Health app. This can help you keep supported records alongside the other health information you choose to store on your iPhone.
The important detail is the direction: Glucose writes supported entries you record in the app to Apple Health. Do not assume that every data type from every app automatically imports into Glucose.
What you can track in Glucose
Glucose is designed for a combined daily log that can include:
- Blood glucose
- Insulin and medications
- Carbohydrates
- A1C and estimated A1C
- Blood pressure
- Weight
- Ketones
Apple controls which Health data types exist, and you control the permissions granted to each app.
Why use a dedicated tracker with Apple Health
Apple Health is a central store for supported health information. A dedicated logbook adds a focused workflow for entering records, applying meal or time context, viewing trends, and producing reports.
Using both can give you:
- A quick place to make and review diabetes-related entries
- Supported records available in Apple Health
- A clearer timeline inside Glucose
- PDF or CSV reports for selected history
Review permissions on your iPhone
Health access is permission-based. You can review or change an app's access from the Health app or iPhone settings. Removing access can stop future writes, but it may not automatically remove information that was already written.
Before sharing an exported report or Health data with another person, check the contents and date range. Health information is personal, and integrations should remain under your control.
What Apple Health sync does not mean
Apple Health integration does not turn an iPhone into a glucose meter. Glucose cannot measure blood sugar through the phone, and it does not provide emergency monitoring, automated treatment, or insulin dosing.
Compatibility and available data types can change with the app, iOS, device, and region. Check the current App Store listing and the permissions shown on your own device before relying on a particular workflow.
