Everything in one app: Etymological Dictionary, an offline reference that works with no internet, a vocabulary builder and a word learning app.

Because the dictionary works offline, the whole database is stored on your device and takes up some space.

Все классно сделано, кроме одного пункта, непонятно почему до сих у всех приложений такая дико беспонтовая иконка, благодаря которой их ещё и путаешь между собой на быстрый взгляд, вообще огонь тема. 🐒🤔

Спасибо вам огромное за отзыв. Мы будем рассматривать это.

What’s new

• New: mark words as “I know it” or “I don’t know it” — from the bottom toolbar on the word page, while training with Flashcards, or by selecting several words in a list at once.
• Marked words get a colour stripe in the lists. You can change this in Settings → Word state display.
• Add the “I know it” and “I don’t know it” lists on the Search page to see those words separately.
• Bugs fixed. Performance improved.
