Good app, inaccurate in some places. I mostly noticed this in the state nicknames game. See, for some states, you added nicknames that, at the very least, are not the most wide spread. Here are all the errors I spotted: Alabama: you listed it as the Yellowhammer State, however most people learn the nickname “Heart of Dixie” Illinois: Illinois is known largely in history and geography classes across this great nation as “The land of Lincoln” as in Abraham Lincoln. Maine: this is very small so forgive me, but though Pine Tree State is co-official with vacation land, most people will only learn one Michigan: largely known as the Wolverine state. I understand the confusion, I didn’t notice until recently. Wisconsin: the badger state is largely considered the official nickname, and the only alternative I could find was America’s dairyland, which is certainly unofficial. Please take this into consideration. 50USStates is well made and very fun, but these little errors are just a tad frustrating, especially if you’re not using it to learn but just as a review. It was very weird calling Illinois the prairie state, because I always learned it as the Land of Lincoln. So many people seem to be using 50USStates as reviews for test, and I would hate for them to trip up on such trivial facts, such as the true nickname of Michigan. Thank you for your time, and God bless- Conner
