User reviews

Awesome, but not perfect.

The app is great; the algorithm put in place to repeat words until you get a grasp of them is brilliant.

Problem is, some of the definitions that you’ll learn aren’t necessarily what you’ll find in a Webster’s Dictionary, which is kind of bizarre. I get it that they’re trying to keep the definitions to a minimal amount of words to help with memory, but many of the definitions seem to be just too short and vague. Then there are some definitions that seem to be a little off...

For example, in the app the word “circuitous” is a noun, and defined simply as “roundabout,” meaning literally a roundabout that you’d drive through. Circuitous can include a roundabout in certain contexts, but it is used mostly as an adjective, and more specifically it means “having a circular or winding course.” Put into a sentence, you could use it as “we took a circuitous route to grandma’s house.” It can also mean “not being forthright or direct in language or action.”

Not a huge deal, but it makes me wonder what other words on the app are a little off. But either way, it’s a great app. I haven’t found another that’s anything like it!

Good or bad

I think it could get better with some more features and some levels.i don’t play this game much longer because it’s not worth playing. I just got a feeling that its going to waste my time on trying to figure out what they are and mean.

I am so sorry for this text

Horrible

Free app, but to see anything or use it, you have to pay to unlock the decks. Sooo misleading.

Fantastic!

Great supplement for your English studies!

Skeptical to start but that changed

Trust me 100% worth a try. Read the science behind it
