Verdict
The clearest difference is price: Dictionary. at Free against Companion Synonyms's $1.99. Dictionary. also leads on review sentiment (91% vs 64%) and ratings volume (15K vs 10). Companion Synonyms's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support and iOS requirement 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. is free to download; Companion Synonyms costs $1.99 up front. Dictionary. sells 1 one-off in-app purchase. Companion Synonyms asks for nothing beyond the download.
Companion Synonyms holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Dictionary. has 15K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 64% of Companion Synonyms's written reviews are positive against 91% of Dictionary.'s, so the app with the better star average is not the one people write more warmly about.
Companion Synonyms ships an update monthly, Dictionary. every 3 months. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
