DuoCards - Vocabulary Builder

This app has helped me learn language so so much. Love it 5/5! But lately it seems to be having some problems that didn’t exist before. It kept saying “connection problem” whenever I’m swiping my cards. Resulting the flame not going up and the algorithm not able to progress. Making me stuck playing with the cards that i already remember perfectly. And when i open the app, i need to refresh like 2 or 3 times I’m able to enter the app because it keeps saying error or something like that. I hope this gets fixed. It’s not that it prevents me from practicing, it just that it’s a little bit bothering. Other than that, i hope this app is available forever❤️ Edit: everything got fixed after i tried to delete and reinstall the app again👌

This is a very great app to learn new vocab! you can also add new words (you never heard or not familiar with) that you want to learn. Thank you for the developer for making this app!

Це інновація зробила революцію у мобільних додатках! Нажаль зараз в Україні дуже впали доходи і не можу придбати преміум. Але постараюсь купити коли будуть вільні гроші. Це дуже круто ваш додаток! Усім друзям показую і рекомендую!

I learn new words with this app every day. I got 1 month premium for free and I’m going to renew it for next months. This is a really useful application.

I liked the program very much, even thought about buying a premium, but then at first I had problems with it freezing, and now I've been learning the same words in a circle for the second week and can't add new ones for even more time, it's a disgrace

This is one of the best programs I have ever used. Can't wait for the offline mode to come out.

I tried both premium and free plans. As a Ukrainian I got a discount at the begging of the war and tried subscription. When sub ended I had no hesitation and paid full price cause this app definitely worth it! Design, flexibility of settings and grammar are perfect! Personally grateful for support and quick responses from tech team.

чудова програма, подобається займатись, навіть без преміума, але останній місяць точно висне на якихось словах програма і треба перезаходити і пропускати ці слова, бо просто не працює вся програма. зробіть з цим щось, будь ласка.

I really wont see their child, pleaseeeee And i wont more tasks)

I'm using the app on my iPhone 15 and when I'm working on flashcards and want to check my spelling, the app freezes. This has been going on for several months now. I regret that I bought a subscription
