Wonderful app
Very thorough educational and good for the vocabulary!!!! As you walk through life you realize how your judged by exactly the kind of grammar and diction that you speak with we live in a world now are people speak more than one language and it's a really good idea to have an app like this to improve your diction. Reading writing and multi facets of global customs become a lot more easier to understand when you have a vocabulary behind you being used constantly to communicate.
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.
