Pope Francis is the 266th Pontiff in the history of the Catholic Church. He's obviously very popular, but the lives of other Popes, like Gregory X, aren't as well known.
Now, there's an 'app' for that. It's called Popes Encyclopedia and with one simple click the lives of every single Pope become available.
It allows users to choose information on the Popes by date, name, country or religious order.
Tapping on the cross will open the main menu. There one can find all kinds of information like the age of John XXIII upon his election, or where Pope Callistus III was born.
Users can also search topics ranging from the longest papacy to resignations and even Popes who have been canonized.
A picture of each Pope can be found along with a card that lists key details about their lives. Popes Encyclopedia is available for iPhone and Android smartphones.
