Shop is different between Mac and iPad can you add features between these two?
I don't know why there is no timed practice and frozen streak in iPad and no owl's suits in Mac can you add these features?
Hope it would be there! :)
The difference is not about Mac and iPad; it's about the mobile app and website. You will have to wait until Duolingo unifies everything. They're doing a lot of A/B tests and they have a lot of things on hand. Things probably won't change in a year or so.
