Unable to figure out how to reverse the card deck to study. I want the front in English and flip to the language I’m learning. I’ve tried googling without figuring out a way to fix this. I’ve used a lot of different studying apps and this is the first that makes it so difficult to flip it.
Developer Response
Thanks so much for the feedback, and I'm sorry this was frustrating. I completely agree it should be much easier to study cards in either direction.The good news is we're shipping an update next week that will make this much more intuitive. Thanks for helping us improve Kioki! We'd love to hear from you once that feature is available.
