User reviews

So helpful

I love this app. Helps me with all my writing needs.

Crashes

Cell or WiFi doesn't matter. It losses its mind. No other app behaves that way.

Offline version

Wish the library was local. So I could use it offline and conserve a ton of battery power. Constant use batters my bars.

A+

Variety is value.

When you “sort of thinking of a word” but can’t quite recall it, this is your tool.

Best app in the App Store!!

I have used this app every day for years. It keeps my thinking sharp, my vocabulary expanded, and is very useful for the creation of mnemonics and acronyms which serve as memory enhancement.
