User reviews

Right to the point

Yes, there are other flashcard apps out there that have every bell and whistle you can think of—but they’re clunky, complicated, and frankly not pleasant to use. Flexi eliminates all of those frustrations and just gets you practicing faster, easier, and in a more fun way. Love this app!

Response from developer

Thank you! I'm happy to hear Flexi has been a good fit for your learning.

plz update Chinese language support

Response from developer

Thanks for your feedback! Decks should sync between iOS & Mac if you're logged into the same account. Please double-check this. If it's the same account and the issue persists, please email me at tomer@flexicards.app so I can investigate.

The best learning app in my life

Progress is obvious. I love it!

Can you add Greek?

I love how there are so many language choices, but I realize this app doesn’t have Greek on the list, and that is the one language I would like to learn right now. If you add it, I would be very grateful!

Many Bugs, Ignored User Feedback👎🏻

This application had a good idea, but the execution is terrible. On top of numerous problems and bugs, the developer completely ignores user feedback. It quickly becomes clear that the app was rushed together with minimal effort just to make quick money. I am warning potential buyers to think very carefully before purchasing an app that contains many bugs and shows such disregard for users. The app does not allow selecting a target language, and the AI generates examples in only one language. Image generation is completely disconnected from the generated examples. You cannot choose multiple translation options for a word, only a single one, and after selecting it, you generate examples. For instance, the example may describe a ship sailing at sea, but when you generate an image, you get a dog sitting in a tree. There is no logical connection between the text and the image. Overall, this is a chaotic product with poor implementation and an unresponsive developer.

Esta aplicación tenía una buena idea, pero la implementación es terrible. Además de numerosos problemas y errores, el desarrollador ignora por completo los comentarios de los usuarios. Rápidamente queda claro que la aplicación fue hecha con prisa y con un esfuerzo mínimo para obtener dinero rápidamente. Advierto a los posibles compradores que piensen muy bien antes de adquirir una aplicación con tantos errores y una actitud tan poco respetuosa hacia los usuarios. La aplicación no permite elegir el idioma objetivo, y la inteligencia artificial genera ejemplos solo en un idioma. La generación de imágenes está totalmente desconectada de los ejemplos generados. No se pueden elegir varias opciones de traducción para una palabra, solo una, y después de seleccionarla se generan los ejemplos. Por ejemplo, el texto puede describir un barco navegando por el mar, pero al generar la imagen aparece un perro sentado en un árbol. No existe ninguna relación lógica entre el texto y la imagen. En general, es un producto desordenado, mal implementado y con un desarrollador que no responde.
