Tea.ch Cards is an application to learn facts with flash cards. It tries to find out how long you can keep cards in your mind. It will expire cards just before you cannot recall it.
Keep cards in different decks. The program will manage and schedules expired cards for learning.
With an Android phone with you, learn cards anywhere and anytime. It is using an adaptive algorithm to find out the time spacing needed.
Flip cards as real flash cards but without the sorting hassle. Flip cards by touching it, sweep left for unknown, right for known and upwards for taking an hour break for the current card.
If you take a longer break from learning, it's no problem if many cards are expired in the meantime, just continue learning. The time spacings will be sorted out. Tea.ch Cards will pick cards that are the most recently expired as these cards are the most likely to be correctly answered by you and can be scheduled into the future.
If you are learning the same words elsewhere? It doesn't matter when your proficiency is improved elsewhere in the meantime, the time spacing will be adapted.
If you have time but no expired cards? No problem, schedule a bunch of cards with the best ratio prematurely.
