No, the app does not work with a physical lock, I am designing a system that can be driven by the app, I would suggest this improvement to Kevin Cross as soon as I finalize the idea.
For now, the app generates a code (configurable from 3 to 8 digits) that is displayed (we can restart a new code if it is too easy to remember), it is only necessary to program the system lock with this code and then once the code lock or code lock is locked press Next.
The app erases the code and shows random codes in all directions (screen saver) for a while, we can repeat this phase as many times as necessary to forget the first code. Personally I focus on the numbers displayed trying to remember what tends to make me forget the oldest.
Problem with code locks: There are only 3 digits and it's all too easy to remember.
As the cage that I am wearing is with built-in lock, I put the keys in a small plastic box (type keychains with condoms it is pile hair the right size) I make a hole in cases at the height of the hole of the key and I pass a first padlock which crosses the box and the key (by the key hole biensur).
Then I make a second hole in the case so that even if we managed to open the box, the key can not switch to the outside and I insert the 2nd padlock which makes me a code to 6 numbers in all.
Sorry for my bad English, I hope you understand me well.
