Verdict
Dictionary.com and Power Thesaurus both sit at 4.8 stars, but that hides the real split: 86% of Power Thesaurus's written reviews are positive against 26% of Dictionary.com's. Dictionary.com's advantage is ratings volume (328K vs 3K) and chart position (#111 vs unranked). On price, rating, update cadence and ads 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
Both are free to download. Dictionary.com sells 9 one-off in-app purchases and Power Thesaurus sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for Dictionary.com against 4.8 for Power Thesaurus. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 3K, 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 86% of Power Thesaurus's.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
