Great app for a unique password. Can take a while to find a password that is memorable in situations where your phone isn't at hand, but is still achievable in relatively short tome and is definitely reliable to give you a secure one. May I suggest possibly looking at a system which impliments simple grammar, so to make it a bit more logical and easier to remember? (PS I saw that if the screen orientation changes when a password has been generated the password resets. This could mean in the scenario where someone puts down there phone to get a device after finding a password, they could lose it.)
Does what it claims, the passwords are random and we can chose the length of the password. Would be better if we could chose how many number or symbols or etc should be there and if any of the elements must be in a string. Overall the app is clean, has a good UI and is easy to use. Good job.
