# Dictionary.com vs MM

The clearest difference is rating: Dictionary.com at 4.8 against MM's 3.6. Dictionary.com also leads on update cadence (every 3 weeks vs every 22 months) and ratings volume (328K vs 10). MM's advantage is in-app purchases (none vs 9) and review sentiment (50% vs 26%). On price, ads and device support there is nothing between them.

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

Dictionary.com holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 26% of Dictionary.com's written reviews are positive against 50% of MM's, so the app with the better star average is not the one people write more warmly about.

Dictionary.com ships an update every 3 weeks, MM every 22 months. The most recent releases landed on September 29, 2026 and September 18, 2026 respectively.
