I’m studying music and I want to make flashcards to learn theory. They would show intervals, key signatures, chords, or they would ask what notes are in a given scale, or show a score and ask a specific question about it. So mostly images, and sometimes text, on the front, and the back would have the answer.
I want the app to show me the cards randomly, and when I flip the card to the back I should be able to say whether I got it easily, got it with some struggle, or got it wrong. (i.e., three buttons).
I want the app to weight the PROBABILITY of seeing the card again based on how I scored it, so harder ones are seen more frequently.
I can’t find a well-reviewed Android app that works that way. One popular one, AnkiDroid shows you the “easy ones” again after 4 days, the “hard ones” after 1 minute and the others after 10 minutes. There seems to be no way to change those values. Since I use my physical cards once or twice a day those don’t work for me. I want random cards with the weighting adjusted according to difficulty. Is there such an app?
Thanks in advance.
