Customer Reviews

STILL no resolution support for the iPhone 6 and 6+

Here we are, 9 full months after the launch of the iPhone 6 and 6+, and this app STILL does not natively support the higher resolutions of the newest iPhones. The dev team apparently had time to make an Apple Watch app, yet they still have t updated the iPhone version to support the HD displays of the iPhone 6 and 6+. Awful.

Additionally, before you even consider downloading this app, click on the "in app purchases" section, and look at all the various ways in which they try and nickel and dime you for features. It's ridiculous.

Please look elsewhere for a dictionary app.

NOT optimized for 6/plus. Keeps begging to upgrade

STILL no support for retina HD resolutions!
And now I'm really tired of this app constantly begging me to buy the premium app or upgrades WHEN I ALREADY PURCHASED ALL THE UPGRADES LONG AGO.
The upgraded example sentences don't work offline! And having to switch back n forth between tabs to view the sentences is friggin annoying! I'm in the subway a lot where theres barely any reception. Not allowing offline examples is just a big flaw.
And I don't need all that nonsense at the title page to slow down the performance when I open the app.

OMG so helpful

For homework sometimes I need to admit I don't know some of the words so k use my phone or I pad or tablet and I use this app to look it up. Whenever i use this app I always get 100% on my homework but when I don't use it I get 100% ... WRONG!!! Very helpful app please use Dictionary & Thesaurus
