Verdict

The call

The clearest difference is rating: Dictionary.com at 4.8 against Pocket Thesaurus's 4.3. Dictionary.com also leads on ratings volume (328K vs 512) and chart position (#129 vs unranked). Pocket Thesaurus's advantage is review sentiment (58% vs 26%). On price, update cadence, ads and in-app purchases 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

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Dictionary.com sells 9 one-off in-app purchases and Pocket Thesaurus sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

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 512, so its average is the more settled of the two. Written reviews complicate that: 26% of Dictionary.com's written reviews are positive against 58% of Pocket Thesaurus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dictionary.com ships an update monthly, Pocket Thesaurus fortnightly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
