Importing cards locked behind paywall

Hard to try this out. There are many card datasets available but can't be used in this app without paying. Found this app on Reddit with the creator saying everything is for free, only to find out in the app that is not correct. 🫤

Great functionality

A fun and easy way to boost your vocabulary regardless of your level. Love the simple design and customisation. The coolest thing is that you can adjust an app to your needs and it really does help you to expand your knowledge of the language
