This is a very simple Caesar cipher wheel. You can turn both wheels individually. You can also lock screen orientation and turn on vibrations.
You can now choose russian or greek alphabet in addition to the latin alphabet.
1.55 : add the ability to block the wheels
1.54 : improving code
1.53 : add greek alphabet (if someone can help me for the greek translation...)
1.52 : fix a bug inside the menu.
1.51 : add russian alphabet (if someone can help me for the russian translation...)
