The app is annoying because you can only see your results when you turn on the device next to your phone. That means you can't show your results to your doctor without taking your device with you. You only have access to your data and history without a nearby device if you purchase some sort of premium membership. This is conveniently left out in the item description. I got this after developing a new arrhythmia post COVID-19 and am a registered nurse who can properly auscultate the heart to detect arrhythmias. I could listen to my heart, hear the abnormal rhythm, and this thing still recorded a "normal" reading. Also the ECG function does not work well with all movements. Other features worked well, but in my opinion it's not worth the price. I have returned!
