I've had tachycardia for decades, and this is the first app that gives me an audible/haptic notification when my heart rate is too high ... instrumental when I'm sleeping or not looking directly at my Apple Watch all the time. I changed my Apple Watch face to "Modular Compact" to use the Beat Watcher (Heart Rate) complication across the entire bottom of the watch, which is very useful when I'm sleeping or I don't have my glasses on.
It's the best money I've ever spent on an app ... for me, it's been a lifesaver. Thanks for making this app and making it so affordable - I regularly promote this app to other veterans with similar heart conditions.
(UPDATE) A few days ago, while I was at the VA Clinic, Beat Watcher alerted me to an elevated heart rate of 127 ... so I pulled out my KardiaMobile 6L EKG device, and I was able to record a tachycardia event. Generally, when the VA takes an EKG, it's normal by the time they settle me into an exam room; however, Beat Watcher allowed me to record a tachycardia event to show my doctor ... without Beat Watcher, I might not have gotten an early warning to the heart arrhythmia and tachycardia episode.
(Suggestion) I want to change the alert tone on Beat Watcher because it currently sounds like every other alert on my Apple watch. Additionally, I had to disable the iOS11 Smart Stack on my Apple watch to keep using Beat Watcher as expected, not a big deal since Beat Watcher is significantly more important to me than Smart Stack.
