# LEO Dictionary vs Thesaurus

The clearest difference is rating: LEO Dictionary at 4.0 against Thesaurus's 1.0. LEO Dictionary also leads on ratings volume (225 vs 1) and update cadence (every 3 weeks vs every 2 months). Thesaurus's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. LEO Dictionary sells 5 in-app purchases, starting at $7.49 per year. Thesaurus asks for nothing beyond the download.

LEO Dictionary holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: LEO Dictionary has 225 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of LEO Dictionary's written reviews are positive against 100% of Thesaurus's, so the app with the better star average is not the one people write more warmly about.

LEO Dictionary ships an update every 3 weeks, Thesaurus every 2 months. The most recent releases landed on October 17, 2026 and September 20, 2026 respectively.
