Use Oxygen level (%) -App in your Suunto watch.

Oxygen level (%)

Mountaineering, Guidance

Oxygen level at the given altitude as percentage of maximum at the see level. Formula: (1+H+(H^2)/2+(H^3)/6+(H^4)/24)*100, with H = -ALTITUDE/7990

      Hi Radku,

      Great little app! I am planning to go up into the Himalayas soon above 5000m. Do you know if with the new Ambit3 has the 5000m limitation set by Suunto been removed? I know the watch can display altitudes higher than 5000m.

        Hi, I don't know if the new ambit has this same altitude limitation as the ambit 1. But you can use GPS altitude instead of pressure based altituded. It should help. Enjoy your trip! Are you going to climb some particularly mountain or just hike?

        Hi Radku,

        Thanks for your reply. If I use the GPS altitude instead of pressure, will you app work still?

        I'm just hiking to Everest Base Camp this time.

        Yes, it should work fine. Just try it out! If you hike to EBC there will be only short part (Gorak Shep and BC) above 5000m.

        I have been up to 6900m and the Ambit2 has worked just fine

      HI,radku, Could you tell me how to load this app to my ambit2?

      Isn't possible to use a FuseAltimeter parameter to get a reliable altitude ? I think I saw a picture from a Suunto watch in a airplane, showing somewhat 24000 feet = 8000 m. Could that be ? BTW: higher altitude = lower pressure = lower partial pressure of oxygen = lower oxygen saturation of the blood. But the body will compensate it down to a given level.

      • radku


        Hi, FusedAlti is not available on Ambit1. You can write your own app using GPS altitude to extend the range of this feature, but the accuracy and battery life will change for the worse. The personal blood saturation it's a combination of altitude and your personal factories.
