Customer Reviews


Very useful app. A must have for students. I love the fact that you can tap the "megaphone", and hear how the word is pronounced. There are also some games you can play to increase your vocabulary. The word of the day is also useful. When I open my app and see the word of the day, I try to use that word throughout the day. I like seeing the expression on people's faces when they hear me speak words they don't know. Overall, it is a great app. I would recommend downloading and try it. You won't be disappointed .

Wonderful dictionary! But SO MANY ADS

Great dictionary with vocabulary improving games and option to create a list of favorite words which is hands. But the amount of ads in the app is getting crazy. They will often block the definition or pop up between every word you search (and you must wait 5 seconds to close the add--which gets really tedious/annoying if you are looking up many words at once).

Aggressive and annoying ads

The pop up ads that are incorporated into this app are necessarily - I get it. But they are aggressive and annoying. Often when I search for a word and then tap it to see the definition, a pop up ad will take over my entire screen and not allow me to exit for several seconds. It's disruptive, unpleasant (the last ad was for a video game I have never heard it), and there was no "x" in sight that would allow me to close the ad. I finally deleted the app in frustration and will find a replacement app.
