We have recently came across a funny little app on the App Store called Miss Diary. The concept of Miss Diary is quite simple: you record your mood every day and, after a while, you will be able see if you have a happy life. Yes, it is the exact same concept as Mr Mood :)
Actually, we are glad that somebody found our app so cool that he wanted to copy it. In our view, it proves that we make good products! Take a look! It is like watching Mr Mood through a distorting mirror...
