Idioma Flash
Idioma Flash is a flashcard building app for learning languages. I use it daily to learn Spanish. You can create decks, easily add cards with live translation, and hear the text spoken for learning pronunciation. You can also export and import decks to csv.
I am currently using this app to practice my daily Spanish vocabulary. When I am reading a book or watching tv and I encounter a word I do not know, I use this app to translate it and add it to one of my decks. Then multiple times a day I practice that deck to really cement the word in my vocabulary.
This app is 100% made by me. I coded and designed every aspect myself. I really hope you enjoy using it as much as I did building it.
