Having an irregular heartbeat at 81 years old, a retired RN so I can read an EKG so I can find out what going on any time I need.

Although functionality is slightly limited, even the free version of this app does exactly as advertised. Measurement is quick easy and accurate within a 1% margin so long as you measure correctly without too much fidgeting. Thanks for a great app!

I want to rate this app higher but can someone please address what is up with the FAQ section?! It is the most bizarre thing I’ve seen. This is an app for heart rate and the FAQ looks straight out of a 90s late night sketchy infomercial. Call 1-800 whatever and get scammed. It’s not even an FAQ page!!! What is going on?!?!

Great app for medium-intensity workouts (which is a relative term, as with most things). The pulse taking capability is a joke - works about 5% of the time no matter how well you try to follow their directions. I also find it cute how they say this is a 7 minute workout when it actually lasts 8 minutes, whoever added the durations of the sets and pauses must have skipped arithmetic class and was too bored to actually time it with a stopwatch. These are minor things though (don’t care much about the pulse rate) and they don’t detract from the usefulness of the app, the smartly designed and well thought-out workout, and the convenience it gives you to do it anytime, anywhere. I enjoy it every time I use it - kudos to the developers.

I started a medical treatment that affects my heart. When I have symptoms it’s nice to be able to visually see my heartbeat. While I understand the app’s disclaimer this is not for medical reasons, it’s still a very good tool that I plan to show to my doctor which may prompt further medical studies.
