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. ### 3/5 — Overall great, with show stopping recent problem *2025-03-10* 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. **Developer response:** please update to the latest version ... we solved your problem thank you again for your feedback and patience ### 5/5 — A great little app! *2023-10-30* This is a super little app for those that don’t have (and don’t want) an Apple Watch… it does exactly what it says on the tin. For me - being very privacy conscious - probably the single biggest benefit is that there’s no need to register or worry about having all your details harvested by some anonymous 3rd party and used for goodness knows what purposes. Integrated seamlessly with my Coospo HW706 heart rate monitor (purchased in 2023) and Apple Health. Yes I’d like a few more features (such as being able to add a custom workout type, for example) - but for the money I’m delighted. ### 4/5 — Feedback *2023-08-07* Should allow option to select activity as sleep **Developer response:** Thank you for your feedback and review. Will try to add it in the next updates. ### 4/5 — Great simple App *2022-09-07* Get 5 stars when integrate a custom activity. While sleep tracking I dont want to select one of the existing exercise modes. ### 1/5 — Could not get to work *2022-01-28* Could not get this app to work wish these was a way to try out apps before you buy…do not recommend **Developer response:** Hi, sorry to hear that. Please tap on Settings, scroll to the end and tap Support. Send us the HR device model you are using and describe the problem you have. Very often the problem is that your device is already paired with another app. ### 4/5 — Nice App *2021-12-08* Nice working and looking app. Thanks! May I add two feature wishes: 1) Could you please add “rowing” as activity. 2) It would be nice if the Herat rate is measured/displayed even when no workout is active. E.g. while cool down, where I don’t want the data to be recorded for Health. ### 3/5 — Great app but *2021-09-12* Great little app that helps me with monitoring my hr from chest sensor. There are few missing functions like adding notes or ability to select type of workout run, yoga, weights. I would like to be able to calculate calories and see battery level of my sensor. There are few bugs when changing screens. Overall great app and I can’t wait to see what future updates will bring. **Developer response:** Thank you for your review and. suggestions We just updated the app, fixed the changing screen bug and optimized it for iOS 15. We already working to add notes for workouts and will soon come up with an update. ### 5/5 — Simple, uncomplicated HR monitor *2020-12-09* I love the simplicity of this app! Nothing being uploaded to 3rd party servers, no ads, and pairs up with Garmin HRM’s (I’ve used HRM-Pro, HRM-Dual). There are some features I’d like to see but then that would add complexity to a wonderfully simple app. **Developer response:** Thanks so much for your review, we’re glad you’re enjoying the app!
