Can anybody understand how it detects cheating (throwing your phone off a tall building)?
Assuming it's just using the accelerometer to detect freefall, is there any way to distinguish ascent and descent? GPS is probably too inaccurate and too high-latency to assist here.
Perhaps it can tell the difference between reaching terminal velocity and crashing into the ground, and it penalizes the former?
- MrDresden 3y agoFirst guess would be that there isn't a deceleration curve when the phone is dropped, like there would be when thrown up.
- HALtheWise 3y agoDropping a phone will result in an immediate change from normal 1g gravity to freefall. Throwing it will involve a brief spike of high-g acceleration in between.

- extraduder_ire 3y agoThere have been a few of those already, for at least a decade. IIRC, there was some weather app that crowdsourced readings from users with certain motorola phones and gave shockingly granular weather.
- ilyagr 3y agoGood question! I wonder if it can detect friction against air.
