# Geometry vs Chemistry Dictionary

The clearest difference is rating: Chemistry Dictionary at 3.9 against Geometry's 2.8. Chemistry Dictionary also leads on device support (3 vs 1). Geometry's advantage is ads (none vs shown) and review sentiment (80% vs 50%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Geometry sells 1 one-off in-app purchase and Chemistry Dictionary sells 5 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chemistry Dictionary holds the better App Store score, 3.9 against 2.8. Both are backed by a comparable volume of ratings — 10 and 8 respectively. Written reviews complicate that: 80% of Geometry's written reviews are positive against 50% of Chemistry Dictionary's, so the app with the better star average is not the one people write more warmly about.

Geometry ships an update every 4 months, Chemistry Dictionary every 9 months. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
