# KingDraw vs Chemistry Solver

The clearest difference is review sentiment: KingDraw at 59% against Chemistry Solver's 0%. KingDraw also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (12.0 vs 15.6). Chemistry Solver's advantage is rating (3.9 vs 3.3). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. KingDraw sells 8 in-app purchases, starting at $1.99 per month and Chemistry Solver sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chemistry Solver holds the better App Store score, 3.9 against 3.3. Both are backed by a comparable volume of ratings — 58 and 26 respectively. Written reviews complicate that: 59% of KingDraw's written reviews are positive against 0% of Chemistry Solver's, so the app with the better star average is not the one people write more warmly about.
