Ratings and Reviews
Too many full screen ads
I used to really like this app , and was happy to put up with the banner ads at the bottom of the screen. Now there are so many full screen ads it is just annoying. I know I can pay for the premium version to get rid of the ads. But I don’t want and have no need for all the other extras.
A great experience this morning! An app for a game appeared, with no timer and no option to get rid of it. Why have a free version of the app that is so hampered by ads as to be unusable. I guess it’s time to get a different app.
This app is AMAZINGLY USEFUL
This app is very useful and helps very much when my daughter is reading and it gives clear definition to what ever word you need it to. But it only does it if u spell it right and then it shows what you might need. It also would be EVEN better if it shows the answer to what phrases mean. I would definitely recommend this app though!!!
Useful, but horrible navigation
Being able to save words to favourites is one of the most useful aspects of this app. However, after selecting a favourited word there is no way of going back to the list of favourites. Instead, you have to go back to the home page. If you have favourited lots of words this means lots of tedious scrolling. It makes the app more or less useless, since you can simply search for definitions on google. The extra options are what add value to the app, yet the navigation of those extra features are terrible.
