# Dictionary.com vs Dictionary and Thesaurus Pro

Dictionary.com and Dictionary and Thesaurus Pro both sit at 4.8 stars, but that hides the real split: 87% of Dictionary and Thesaurus Pro's written reviews are positive against 26% of Dictionary.com's. Dictionary and Thesaurus Pro also leads on in-app purchases (none vs 9) and ads (none vs shown). Dictionary.com's advantage is price (Free vs $9.99) and ratings volume (328K vs 2.6K). On rating, chart position and device support there is nothing between them.

Dictionary.com is free to download; Dictionary and Thesaurus Pro costs $9.99 up front. Dictionary.com sells 9 one-off in-app purchases. Dictionary and Thesaurus Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for Dictionary.com against 4.9 for Dictionary and Thesaurus Pro. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 2.6K, so its average is the more settled of the two. Written reviews are what separate them: 26% of Dictionary.com's written reviews are positive against 87% of Dictionary and Thesaurus Pro's.
