Firstly, this app has example sentences that other dictionaries do not have. Next, it also has synonym discussion for some words which only happens in this app. Finally, it also teaches you how to pronounce the word correctly which some dictionaries do not have. The only drawback would be the lack of British spelling for certain words like color.

If you don't have the paid version many of the ads that pop up are scams or have malicious code. The "Google identified a virus just click yes" scam pops up a lot. They aren't careful who buys ads. Taints the experience.

Good app; it's exactly what it says it is, and it's a dictionary. Unfortunately, it loads bad ads that try to scam you, and they can be pretty startling, especially because an ad can play if you tap a word on accident. Also, it would be nice to be able to navigate through the dictionary by alphabet, rather than by searching the exact word.
