CodeBreaking Ultimate ADV app for iPhone and iPad

CodeBreaking Ultimate asks you to decipher a secret code with as few as possible trials (the technique is the same of MasterMind). For each trial you get information about how many digits are right and how many are in the right position.
In addition the app informs you about your progress (red bar in the figures) and a comparison with what the app should have done (green bar in the figures).
You can setup how many digits (between 3 and 5) and how many symbols (between 7 and 16) can be used to generate the secret code. You can also decide if symbols can be repeated or not.
You can also setup how many trials (between 6 and 20) and how long the match can be (between 6 and 20 minutes).
User can choose between 8 symbol fonts which to use.
