Children don't understand much rotation speeds in rad/s in the raw data of the gyroscope. So I add "turns" where they can see a number of turns (signed - positive left and negative right and absolute). The smartphone should be kept horizontally while turning ...
The example shows 3 turns left and then 1 turn right.
I experience some flickering, apparently when “Turns around z” and “Absolute turns” are different. Please find attached a screenshot on an iPhone.
“Absolute turns” typically and almost immediately shows a reasonable value again (of about 6 here). The scale of the vertical axis also frequently jumps to four digit values, however, I could not catch it in a picture.
