Door Code Notifier notifies you when you're near a friend's place and shows you their door code.

No longer will you have to look for the code, or call your friend: the information will automatically come to you when and where you need it!

The notification also presents handy 'Text' and 'Call' quick actions.

The interface to enter the data is very simple and clean.

This app is compatible and works well with Android Wear™.

This app is open source:
