“Send Me To Heaven (officially stylized as S.M.T.H.) is an Android application developed by Carrot Pop which measures the vertical distance that a mobile phone is thrown. Players compete against each other by seeking to throw their phones higher than others, often at the risk of damaging their phones.
Players are instructed to throw their phones as high as they can, with minimal rotation for most accurate results. The maximum height is calculated via the phone’s accelerometer. Because some phones have accelerometers positioned off-center, any rotation in those phones may confound the data. “Cheating” by throwing a phone from a tall building typically returns an error message. The app’s calculations keep track of how long the phone takes to rise and fall, and an error message is displayed if the distance fallen exceeds the length of the ascent.”
