The interface is great because it anticipates the word as you type and if your French spelling is weak - like mine is - it saves a lot of time." -User review Follow us on Twitter and become a fan on Facebook for app news, language learning tips, and more: http://www.twitter.com/ultralingua http://on.fb.me/ifI8Hy

Verdict
The clearest difference is price: Dictionary.com at Free against Collins's $14.99. Dictionary.com also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (328K vs 635). Collins's advantage is in-app purchases (none vs 9) and ads (none vs shown). On rating and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Dictionary.com is free to download; Collins costs $14.99 up front. Dictionary.com sells 9 one-off in-app purchases. Collins asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.7 for Collins against 4.8 for Dictionary.com. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 635, so its average is the more settled of the two. Written reviews are what separate them: 60% of Collins's written reviews are positive against 26% of Dictionary.com's.
Collins ships an update every 5 months, Dictionary.com every 3 weeks. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
