Can I sync past data into Cardiogram?

When you install Cardiogram, launch the app, or create an account, we can import up to the past 14 days of heart rate and health data, depending on the device and available permissions.

• This limitation applies to most phones and wearables

• It is based on what your device’s health app (like Apple Health, Fitbit, or Garmin Connect) allows third-party apps to access

🔄 Keeping your data up to date

To make sure your Cardiogram timeline stays current:

• Open the Cardiogram app at least once a week

• This prompts the app to import and store any new data from your wearable’s health data source

❗ Missing older data?

If you’ve been using Cardiogram for a while and suddenly notice missing data:

• Make sure you're signed into the correct Cardiogram account

• If you're still seeing gaps, feel free to email us at [email protected] and we’ll help you investigate
