By far the best I’ve seen so far. It’s actual Yoruba, not the Anglicized version of Yoruba that I’ve encountered different places...when I saw Fitila...instead of Lampu, I knew this was the app for me and my son. The voices are forcefully employed in the pronunciations, which my 3 year old responds to enthusiastically. (It might be jarring to western ears) I look forward to updates.
