Doesn’t work as promised

Creating decks using their published documentation is a nightmare and don’t work. I tried every AI to generate language decks but app doesn’t import them. I manually check everything and decks follow their described format precisely, still app don’t see cards when importing

Used to be good now locked behind a pay wall to get a basic app idea, flashcards shouldn’t cost $15 a month

Service keeps getting worse with each update.

The maximum daily reviews for non-paying customers is being lowered with every single update. Today I did my review as normal and was stopped after 80 cards even though the daily limit was 100 cards before. Before it was 100 cards, I never even hit a limit. If you want people to pay to use your service, make it a paid service from the start.
