5 stars: Nice and simple to use and it's very accurate
5 stars: Please put in an option to use the sensor that is installed on my phone instead of my camera.
5 stars: this is the best Heart rate app I've seen in a long time. No bloat, continous measuring, a graph background to measure intensity, can toggle flash on or off and syncs with Google fit. Excellent. i don't rate many apps but this is with my time so others can experience the app that allows others away. It would be better if an audio beep was added for the heart rate but this is really good
4 stars: People say its crappy, but I personally think that its great but not perfect! Im wondering why you need a bright background... oh well! ok, i think that you should add heartbeat audio and recording option to save! i know you can hear \
5 stars: I like this app. it even detects my heart murmur. it can be annoying with the amount of light it needs,though I understand why it needs what it does.
4 stars: I love this app, especially since it can be turned and viewed full screen. I feel that it is lacking a key componant though and that is arrhythmia detection like Cardiac Diagnosis. this would be #1 with a feature like that added.
3 stars: its a good app but, this is not the apps fault but i have to get in a good position so it works good enough and i just think it should learn to even out the bpm so its not all over the place cause i have to figure out the average of it
5 stars: WOW! Not bad at al...
