What about the web app?
It's coming back, and sooner than you'd think. The web app relaunches the moment the mobile app is ready, so even if app stores take their time approving us, you're studying on day one either way.
And it's staying for good after that. Some of you don't want another app eating your storage, and if you're on wifi most of the time, you don't need offline downloads anyway. Open a tab, everything's there. Same account, same progress, whichever way you use it.
