Works well

Works well for recording heart rate during workouts with good privacy protection. Would be nice if it could also record GPS position so I could correlate where I was on my ride with the heart rate data.

Overall great, with show stopping recent problem

I’ve been a happy user of Cardiogram for some years, but as of the most recent update (in February 2025, I believe) it’s no longer writing HR samples to Apple Health for me. This is the only reason I use Cardiogram, as a kind of relay between my Bluetooth HR strap & the Apple Health database. (Which is to say, I don’t use its “workout” features.) I’m not able to access the Facebook page that the App Store support links to, so am posting here to give some visibility to the developer. Thanks.
