Mik. K. Feb 25, 2017

Needed a readily available oximeter and now I don't have to buy and lug around an extra piece of equipment. Yeah ( 30 times).

Cou. H. Feb 22, 2017

Blood pressure is way off but other are accurate for me though.

Hay. j. Feb 12, 2017

I feel as if the oxygen and heart rate is correct but the blood pressure just seems to be random numbers

Fra. M. Feb 25, 2017

Had to enable camera access manually. Would have been five Stars otherwise

One that really works@

Eli. C. Dec 18, 2016

Is the best product in the market

Joe. T. Nov 30, 2016

It's a nice app. The heart rate is accurate, the blood oxygen looks accurate but I have nothing to verify it against. The blood pressure seems to be random numbers, I checked against a sphygmomanometer and it wasn't even close. Today I noticed it's using 2% battery when I haven't even started the app since the phone was last started. I can't afford a battery hogging app that will only see occasional usage.

An addition of graphic display of different measurements in time would be nice.

Pie. K. K. Nov 6, 2016

The emotions aren't really accurate in my opinion, but the rest is amazing!!!

Lar. F. Dec 22, 2016

Ads cover up the results

Ale. A. Nov 30, 2016

not sure why it eats battery like that

Mic. E. Nov 15, 2016

Very accurate and useful

Wil. F. Aug 24, 2016

Bogus blood pressure values. Read 165/115 which was way higher than what my doctor read with a cuff today. Moved my finger and it read 120/85 which was much closer. Heart rate seems to be on target compared to my Galaxy S7 pulse oximeter. SpO2 read 97% consistently.

A. G. u. Oct 19, 2016

App is completely useless since ad covers the entire bottom of the app, including the start button

Bel. A. Sep 14, 2016

Not sure about the accuracy, but close enough.

Nes. Q. Sep 26, 2016

It helps me greatly to control my anxiety
