I tried logging into and it sent me 12 emails with codes to verify my email address. So I can’t log into and there is no way to get help for this issue ### 5/5 — Cardiogram tracker *2025-10-21, version 3.7.48* Excellent application 5 star with reports and logs ### 1/5 — Lost *2025-10-05, version 3.7.48* Unbelievable, my information was gone, only response was it only happened to some Fitbit users. Unfortunately, mine was completely wiped. This is what you get when you buy the premium no excuses shouldn’t happen. An app should not be a beta test ! I did reach out to the individual that informed me of the problem. He never did apply to my second email ### 2/5 — According to Cardiogram I should be dead! *2025-10-01, version 3.7.48* I am super fit 55 yo man. My VOmax is 36. I have perfect BP control and a clean recent ECHO. I run 5 days and do a 6 mile ruck with 55 pounds every week. Yet Cardiogram health score steadily drops as if I should be in a retirement home. TODAY, my score literally went from .7 (really) to 0! Yes, ZERO! I used this app for years and it was useful but expensive. Today, I cancelled it and won’t renew. When my subscription is done, I’ll be deleting this app. There are better options for way cheaper. DONT waste your money on Cardiogram. ### 4/5 — Tell me another joke! *2025-08-25, version 3.7.46* This has to be one of the worse apps there is. I paid good money for the premium app. It works when it might want to work. Constantly get “network error 0”. There is absolutely nothing wrong with my network, period, so it has to be on their end! I have over 700 apps on my iPhone, and this app is the only one that causes any problem! Also can’t load data “reload”. That does not work either. Have totally removed app and reinstalled app several times. Does not solve either issue. Please, do not waste your money on this junk app! EDIT: Tech support is absolutely terrible! You can submit a teck support request and they will respond once. They don't fix the problem and they don't respond to further support. Please don't get sucked in to paying for premium service, you will be disappointed! EDIT: I was finally reached out to by support and they completely removed my issues. Good job. Thankx ### 1/5 — NOT Free *2025-07-31, version 3.7.46* If u r looking for something free this is NOT it. U cant even take a reading unless u pay. I wasn’t looking for all the other bells and whistles just some to track my heart rate for my doctor I been out of work for 4 month can’t afford another bill There wasn’t even a trial period. ### 5/5 — My heart's best friend *2025-07-10, version 3.7.46* Kardia what marvel ### 2/5 — Unknown price until…. *2025-06-19, version 3.7.46* ** Not a review of app functionality ** I don’t sign-up for anything if I don’t know the subscription price. While I understand I can use the app for 30 days for free; I don’t understand why I have to sign up before knowing future cost. It’s not in the App Store description, and still unknown until after one signs up (I assume as I never got that far). This is a problem with many apps not just this one — but it’s a deal breaker for me. Apps capture my PII, then reveal cost. No thanks. ### 1/5 — Incorrect info *2025-05-29, version 3.7.45* Reports shows everything in green but overall I’m at risk…not sure what this app is telling me at this point. Kind of useless tbh. ## Frequently asked questions about Cardiogram ### What does Cardiogram: Heart & BP Logger do?
