This app presents Dante's Purgatorio in multiple translations, both poetry and prose, as well as the Italian original. You can swipe left and right to change translations or compare the original. Going to settings and choosing "twin mode" will allow you to look at two translations side by side if your screen is wide enough.
I wanted to read Dante, but I wasn’t sure which translation to read, so I made this so that I could read them all at once. More translations are coming!
