*Translation functionality can be activated with a one-time in-app-purchase. Please note that translations are provided for the words looked up and not for definitions. Translations are provided via Microsoft Translator, which does not have a 100% accuracy rate, especially for isolated words without context. An upcoming update will include the ability to test translations in your language of choice before paying for the in-app-purchase, to help you better gauge the value of the functionality before paying.

Really good app

Hello, if you come back to this app I will be glad I like to use this app it’s really good but I would be to see several options with definitions on english just add from another sources because your standard definitions so much hard to me I try to learn new words every day I think u have guessed that English isn’t my the first language, and yea I’ve seen features like add own commentary on the bottom for words and I’ve bought the extra pack for translate from English to my native language but it’s not helpful for me unfortunately I need English descriptions for understanding and learning. And one asks yet if you can change your repeat system it would be great because now it isn’t working well when I repeat my new words it is impossible all words show random, thank you

Favorite Vocab app

I’ve used this for years and love it. Most vocabulary apps are about flashcards and flipping a word with an answer. The ability to look at definitions and type in the spelling has worked well for me. Hope more features are added—like controlling when you want to work on words that you haven’t come across yet. In my word vault I have over 10,000 words I’ve selected from years of reading that I like to keep fresh. However, the app doesn’t allow me to control when it goes back to old words. I’ve had this app for a couple of years and have only gotten to around word 7,000, mostly the result of inactivity for a couple days or so which means I have to go back over words I’ve already learned. If you could provide more control over this or create a feature when the app doesn’t go back over old words at midnight every night that would be great.

Want to become well-spoken?

This app is so incredibly user friendly, yet it includes the features you wouldn’t even have realized were essential. I’d been taking screen shots of all of the words I look up while I am reading or watching shows that I find beautiful or that I hadn’t heard before. Now, I just type it into the app, and voila, it’s recorded in my “vault”. Then, I review the words with its awesome review system, and words I get wrong go into the “weak” folder so that I know to work on those ones more until I get them. Long story short, I am actually improving my vocabulary in an effortless and sort of addicting way. I can’t rave enough about this app. I ABSOLUTELY LOVE IT.
