Previous issues resolved, however I am now experiencing a situation where Cardiogram is not updating for many hours (12 hours currently). I have forced a resync, force-quit the app, cleared the cache, and restarted my phone to no avail. The app associated with my watch is up-to-date and showing me real-time info, Cardiogram just doesn't seem to be updating.

Thanks for your patience! We've released an update that fixes the crash and login issues. Please update Cardiogram in the Play Store or try reinstalling the app. Let us know at hello@cardiogram.com if the issue continues.

Premium user here for a year now. The samsung 7 ultra will not sync to the phone. The watch keeps prompting you to "sign in on phone" even though I'm already signed in. When you hit that prompt, it opens the phones page to install the app again. I've even uninstalled the app multiple times on both the watch and phone. I've noticed their ratings have reduced dramatically, most people with similar syncing issues. As of this time, I'd not recommend people to purchase the subscription.

Those ratings are from a while ago we've since fixed these issues multiple times. However, if the problem is isolated to just you, we would love to hear from you so we can troubleshoot. Can you send us a message to hello@cardiogram.com?

I have loved this app, and I do pay for the subscription. In recent months, there have been quite a few glitches recording my heart rate and syncing from my watch as well as syncing activities from Google Fit. I contacted Support, and while they provided various suggestions, all of which I tried, the excuse is now the "third-party apps." Sorry, I expect more from a paid app, and if you can't deliver what you advertise, then don't charge for it.

Hi Natia. This isn't the experience I want for any user. I'm curious to know who you were working with to find out what is going on. I don't want you to pay for something you can't use properly, either. I think I may see your email thread here from another advisor I'll reach out to follow up with you. - Kevin
