Hi there! I see you mentioned that you paid for your Cardiogram yearly subscription on November 25, but the app has completely stopped working. To help you better, could you please share a bit more about what exactly happens when you try to open or use the app? For example, do you see any error messages, does it crash, or does it just not load data?

From what I know, Cardiogram was actually removed from the App Store and Play Store in November 2025, and stopped functioning around that time, which directly impacts the app's availability and functionality. This could explain why your app is not working despite having an active subscription3 10.

Here’s what we can do:

1. Check if you are running the latest version of the app you have installed. If the app was removed from stores, updates may no longer be available.
2. Try uninstalling and reinstalling the app to see if that resolves any loading or error issues.
3. Confirm your subscription status by checking your payment and subscription details through the platform where you purchased it (like the Apple Store or Google Play). Since the app is no longer officially available, subscription activations or renewals may be affected.
4. If the app is indeed no longer supported, consider requesting a refund for your subscription. According to official info from Cardiogram, refunds can be requested due to service discontinuation3.
5. Look into alternative apps that offer similar heart rate and health monitoring features since Cardiogram is down permanently4.

Let me know if your app behaves differently or if you need guidance on the refund or alternative options! Are you seeing any specific messages or issues when you try to open or use the Cardiogram app?
