iDotto is an audio guide of Rome like no other! It always knows where you are and tells you what are you looking at, adding detail to your preferences, your interests and the duration of your stay. If you go back to a place you already saw, iDotto will remember and won’t repeat the same things again! iDotto manages over 3,000 passages with ‘technological intelligence’ tells you the history and events of the 900 microcosmos which the centre of Rome has been divided into.
