About

Meloji

Read full description

Dear traveler! I created this app and continue to develop it primarily for myself, so it contains nothing superfluous. Who is this app for? 
It’s suitable for people looking for a free, unlimited tool to learn languages, prepare for exams, or explore all kinds of areas of this vast world. Instead of storing and flipping through notebooks in the hope of a barely lingering fragment of memory, you can simply flip through flashcards. It’s convenient. The app has a subscription. 
It is completely optional. I tried to strike a balance between not limiting the free features and ensuring that the subscription is useful and enjoyable for users who want to support me. A subscription unlocks access to additional app features, such as: 
- smart import for creating flashcards from photos and files (PDF, DOCX, XLSX, TXT), including articles and lectures;
 - automatic translation;
 - text-to-speech;
 - other useful features and learning modes. By the way, there’s a cute cat in the app that you can pet! I hope you like it (≧◡≦) Terms of Use: https://www.apple.com/legal/internet-services/itunes/
