Update – LockBox Review

Is there any way you can update this app? I want to still use this app but I'm having a problem with entering my password. The background is the color black and the numbers are black as well. Can you change the color of the numbers to white so I can enter my password to use the app again? Update this to run on IOS 11.0.2 please. Thank you
