Easy to use, very handy vs book. Good options for tracking symptoms including time and duration of episodes. I gave it a four-star instead of a five because of the constant login and suggestions for biometrics. To be honest, it became a nuisance, especially for someone who doesn't feel well in the first place. LoL 😊 An option for tracking blood pressure, would be great... kudos to developers

would not register my device. when I hit link to register it went to register log book. Took the scan of the log book but it would not take the start date. The done link... which is not lit. doesn't work. The app recognizes me back but nothing works incl. the link to add notes. Totally frustrating. Will end up using the book but probably will not be great at logging symptoms since I am in Afib 24/7 and what's suppose to feel like a symptom is normal to me except shortness of breath I feel it

This app is pure garbage. I'd give it zero stars if I could. It forces logout all the time (and don't give me any nonsense about regulations -- there is NOTHING in HIPAA which requires that). It doesn't support vaulting of passwords (so I've had to make the password easy to remember since I cannot copy and paste from my vault into the password field). I've had to do multiple password resets just to keep using the app. Biometric integration is bug
