# Dictionary.com vs Wikipedia

The clearest difference is rating: Dictionary.com at 4.8 against Wikipedia's 4.3. Dictionary.com also leads on ratings volume (328K vs 6.3K). Wikipedia's advantage is in-app purchases (none vs 9) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Dictionary.com sells 9 one-off in-app purchases. Wikipedia asks for nothing beyond the download.

Dictionary.com holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 6.3K, so its average is the more settled of the two. Written reviews complicate that: 26% of Dictionary.com's written reviews are positive against 55% of Wikipedia's, so the app with the better star average is not the one people write more warmly about.

Dictionary.com ships an update monthly, Wikipedia every 2 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
