Ever wanted a key fob simulator, who wouldn't ? :)

Simulator runs on iPhone and presents as a key fob with a few shortcomings noted in the "about" notes, works great with TI's Multitool.
App is free and code is on Git Hub if interested in seeing how to program an iOS device to be a BLE Peripheral.
Cheers!
