Unlike Android, Apple’s mobile devices know which way is up E-mail Tweet Facebook Google Plus Linkedin Share icons by Philip Elmer-DeWitt @FortuneMagazine May 22, 2014, 10:32 AM EDT FORTUNE — On Wednesday, developers at Game Oven released a choreography app for Apple’s AAPL iPhone called Bounden. They had planned a simultaneous release for Google GOOG Android devices, but late in the game they discovered a problem, as producer Eline Muijres explains on the Game Oven website: We have been developing Bounden for Android alongside its development on iOS, and have tested the game on a number of devices. It was only a week ago that we started expanding our list of test devices, after we quickly discovered that: a) some devices had ‘broken’ gyroscopes that didn’t work on all axis,b) that some devices were faking gyroscopes by mixing and matching the accelerometer data with compass data, orc) that some devices did not have a gyroscope at all.

Shoot us an email to receive an Android build of the game and help us find out if it works properly on your device. Be sure to mention the model of your phone in your email!) LINK: Bounden for iOS.
