I have asked the developers to allow us to save the words through normal copy paste methods. Months later, they have summarily ignored my request. This greatly limits the usage of the app for me and my purposes. edit: updated and it works! hallelujer!
Developer reply
Thank you for your feedback, and we apologize for the delay! Copy-and-paste functionality is now available. We're also working on exciting new features, including interactive quizzes to help users learn and understand the meaning of each word. We appreciate your patience and support!
