Spire measures respiration

If I got this right, Spire is a wearable, logging, accelerometer. It infers respiration from the acceleration caused by chest movement. Does it not get confused in turbulence when in a plane?

I read that if you wear it while running, it stops inferring respiration and starts to count jolts as steps. Does it switch over to 'step counting mode' in a glider?

If it does what the marketing says, it is amazing tech, but it seems 'too good to be true'.
