Just got the vivosmart4, specifically for the PulseOx. Only after use I realized I can only use if I consistently check the SpO2 manually or the four hour sleeping period. I can imagine there's some battery life setting to this, but as a pilot, I'd like to be able to manually select a range of time to have the Pulse Ox frequently running (while I'm flying).
It would be great if a future firmware release could address this because it would be a massive safety feature of the vivosmart band can start vibrating at its full power if it detects my oxygen sensor is low.
