new update is very not user friendly

I just want to create a card with a word and its translation. The latest update has made this action so inconvenient; I need to do so many extra steps. Delete everything the AI has done and write my own examples, because I want to use my own, but the AI does this without asking. I’m finding it very inconvenient to use. Please understand that this update hasn’t made anything easier. I’m already thinking about looking for other options. It’s a real pity — everything was fine before this update.

Thank you for the feedback, and I’m sorry the new flow has added extra work. In your deck’s settings, under Personalization → Automatically generated fields, you can disable the extra fields so new cards contain only the word and translation. You can still add your own examples. The goal was to reduce repetitive generation as more fields were added, and to offer separate cards for different meanings instead of combining them into one card. I’ll think about how to make these choices clearer. I hope the settings help in the meantime!

A few…

Honestly, with this new update, the app feels so much more alive especially with the pronunciation feature. Really hoping the dev keeps this momentum going and drops even more cool stuff. But I do have one suggestion: give us more flexibility with languages. The current list is kinda limited, and since iPhones already have built-in voices, why not let us manually add words outside the default options? Especially in the translation section ,users could add their own definitions. That would totally remove the barrier that's probably stopping a lot of people from subscribing. Plus, flashcards could be used for everything - math, physics, chem, or even bio stuff that needs images. So yeah, please add more customization options. Appreciate you reading this!

Thank you for your feedback! Persian isn't currently supported by the Gemini AI models used in the app. I'm monitoring updates and hope to include it as soon as it's available. Appreciate your patience!

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.

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!
