Oximeter

It does nothing. It gets stuck on determining your altitude. I have full signal and it says there isn't enough. There's an option to set it manually, but there's no way to confirm, so that doesn't work. So, it's under usable. Wish I could give it less than 1 star. The error messages don't even use proper English.

People don't understand this app has nothing to do with air quality. It only calculates the partial pressure of oxygen relative to standard temperature and pressure at sea level. It does not measure oxygen but estimates/calculates it from the altitude determined by the GPS coordinates. It works when it can get the GPS coordinates and determine ground level above sea level.

Can't automatically find my altitude, won't take my manual input, doesn't have buttons like it should (Set, Retry). Can't move past the first page. Total waste of time.

last app update...a long time ago. you should choose title of app with care therefore -4☆. this read GPS altitude automatic or manual. deny allow GPS read and she go to manual input. be aware no ok button appear. after select altitude just press right down corner(PRETEND there is a button ).

The app is useless, get stucked when you try to put the elevation manually, while the app does not get the elevation automatically from the position!!

Great app. Only problem is there is not an option to use feet instead of meters when manually setting the altitude

I want to manually see submit my altitude there's no submit button. I'm uninstalling because I can't get any further

It does not test your blood Oxygen levels. Only lets you know your altitude and approximate % quality of oxygen in the area you are in.

This app does not check your oxygen. It says it finds your altitude and then makes it up.

Tried to enter altitude manually but could not, though it says option is available.. could not go further

Not a oximeter. Its a calculator to determine what would be the oxygen level in the air at a give a Altitute.

Does not work. It just goes to 99 regardless if i touch the sensor

Even with no finger on the sensor it shows the same result.

App is good, it tells the oxygen level in atmosphere but i doubt if it is accurate

There is heavy smoke in my area from a fire in Spanish Fork Utah. There is no way the breathable air is 82 percent. Is there a way to get the correct reading with this app?

1star as not able to post with 0 star, Worst download ever. Uninstalled within a second.

Waste of time it vives altititude oxygen levels not actual. Even that was not shown on my device

Unusable. No button to start the measurement.

great tool when going on a recent trip to the mountains!

it is just a gimick app...it won't show your oxygen saturation level...

We are traveling to various elevations, this app makes it interesting

unfortunately this app. uses meters instead of feet. not what I was looking for

Not bad....if other features included it would be awesome

Only measure the oxygen It should be measure the pulse rate etc

Pulse oximeter major usage is missing ignore it. No stars

ZERO 0 ZERO STARS Waisted my purchase bought meter because had app and it is WORTHLESS. DONT BUY THE METER DONT WAIST DATA DOWNLOAD
