Essential App

It is an essential app on all of my devices. It is very helpful for learning the meaning, pronunciation, usage, synonyms etc. “Word of the Day” and challenging games are excellent!

OK - Ads & crashed a bit

I really want to give this 5 stars but it had those annoying popup ads every first word you search and for some reason when I would try to “go back” a couple of pages it would crash every time for me. Sadly I got annoyed of this so I switched to another app but I think these are easy fixes so hopefully they do! Otherwise, this app is so visually appealing, easy to use, and offers fun word games (in a non-obnoxious way)!
