IMPORTANT - If you updated to 1.2.0, please install the update to 1.2.1. There was a critical bug where on pre-Lollipop devices the device would never reset the PIN to what you chose. If you are locked out on v1.2.0 please use unlock PIN 192458799.

This PIN has been changed in v1.2.1.
I have posted an updated version of the app, and am attaching it here if you don't want to wait for it to come through Google Play. I am so sorry about this! Android Studio didn't report that a method I used was only available on API 22.
