Hi! I created RemeberFast because I couldn't find a simple flashcard app that worked the way I wanted. It's a straightforward way to learn and remember new words using good old flashcards, but with some helpful modern features. And the best part? It's completely free to use with no account or sign-up required! What RemeberFast does: • Creates smart flashcards that adjust to your learning • Makes it easy to add words you want to learn • Lets you hear how words should sound • Helps you practice both sides of the translation • Keeps track of what you're learning • Works instantly - no registration needed • AI features: translation & corrections • Listen pronunciation while practicing I'm working on adding: • Folders to organize your words better • A simple calendar to see your progress • Syncing between devices • A premium plan with additional advanced features (coming soon!) The app will always remain free to use with all its core features, with no account required. In the future, I'll introduce a premium plan for users who want extra capabilities, but the free version will continue to be a complete and powerful tool for language learning. Who might like RemeberFast: • Students looking for a no-nonsense study tool • Travelers wanting to learn basic words • Anyone who prefers keeping things simple • Budget-conscious learners who want a quality free tool • Users who prefer not to create accounts I built this app to be the kind of tool I wanted for myself - simple, effective, and free. I hope you'll find it just as useful as I do! If you have any questions or suggestions, please don't hesitate to reach out. Your feedback helps make MemoWords better for everyone. Happy learning!
