# Advanced Dictionary&Thesaurus vs Pocket Thesaurus

The clearest difference is ads: Advanced Dictionary&Thesaurus at none against Pocket Thesaurus's shown. Advanced Dictionary&Thesaurus also leads on rating (4.7 vs 4.4) and review sentiment (82% vs 62%). Pocket Thesaurus's advantage is update cadence (fortnightly vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Advanced Dictionary&Thesaurus sells 2 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.

Advanced Dictionary&Thesaurus holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Advanced Dictionary&Thesaurus has 4.6K ratings behind it against 577, so its average is the more settled of the two. Written reviews point the same way: 82% of Advanced Dictionary&Thesaurus's written reviews are positive against 62% of Pocket Thesaurus's.

Advanced Dictionary&Thesaurus ships an update every 2 months, Pocket Thesaurus fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
