Oximeter

It's perfect, I work at a overdose prevention site. need it every day.thanks.

To many stupid ads

O2 digit in notification bar would be nice

Liked it, but there's a to address too many ads.

Good

Google aps

Doesn't really do what it leads you to and is an adware for a shopping site.

Good app.

This just takes the altitude from your GPS and tells you what percentage of the air is oxygen at that elevation. It also shows the boiling point if water. There is info about Acute Mountain Sickness but it is written in poor English. This does NOT calculate your blood's O2 levels, which is the most critical for developing AMS.

Adds are on

Pretty useless

It can get the elevation with GPS but it won't take manually entered elevation. I guess I have to drive to the summit of Pikes Peak to get the o2 level up there.

Doesn't allow manually setting. Numberpad appears but no input.

Its working but not accurate readings i hope

good

It sets altitude automatically via gps and location to 1453meters!! (It won't take manual input for altitude), whereas i am on the beach in south china sea!!! Uninstalled... LG G PRO2 and my fone gps functions perfectly with google maps and other gps and altimeter apps....

Useless

An app worthy of sitting on my home screen (most don't make it).

It can get the elevation with GPS but it won't take manually entered elevation. I guess I have to drive to the summit of Pikes Peak to get the o2 level up there.

Use a lot on travels

Worked alright for me. But I need this app since I have asthma

Manual altitude entry is busted. No key on the keyboard works. The display only shows percentage of pressure compared to sea level. Would be nice to show actual O2 partial pressure at elevation.

Acurate altitude and O2 levels are excellent.

Cool apps

Yes **

My Samsung Note 4 has plenty of GB available but the app insists it cannot install on external SD card. Too bad

Loved it works well

Nice

Love it. I was searching since long back

Works great!

How long is it meant to take to work?Still waiting and nothing, still locating...15 mins already!

After installing on Samsung phone w/version 4.1 android os keeps freezing my phone. Uninstalled it phone works perfect. I live 6ft above sea level program says I'm 130ft above sea level. Went to the beach at sea level same
