Librivox

Librivox is  a free audio book site that also has an app and podcasts as well.  Once you set the language to Latin a decent number of audio texts become visible.  I think there may be more texts on the website than in the app.  I would recommend started with the medieval translation of Homer, then the Historia of Apollonius and then Caesar.  I also like listening to Vergil's eclogues and Georgics in the garden because it is so completely, nerdily glorious.
