This app is excellent again the music monkey cheering me on is the best. Sometimes I wish the timer was a bit slower for the matching intervals game because at the beginning of learning I am a bit slower... however I know I’ll get faster over time! Updated back to 5 stars. Original review: I was automatically logged in for several months however it logged me out and now I forgot my password. All my scores are now gone T-T as there is no button for forgot password. The game itself is awesome and works well. Especially the cute happy music monkey. Highly recommend the game for fun learning. ***Update: I created a new account and I wasn’t able to login to the new one either... “cannot connect to server,” it says. Tried resetting ipad and no luck. Internet works as usual. Hope someone can help with this. *****update x2 I created a new account however it gave the same error message “unable to connect to server” so maybe it’s not on my end. I restarted my iPad and reinstalled the app. ## Frequently asked questions about Bastien [Interval] Flashcards ### What is Bastien Interval Flashcards?
