# Chem Calc vs Markdown.md

Chem Calc and Markdown.md are too close to call on the numbers: across 8 compared parameters — price, rating, ratings volume and ads among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Chem Calc sells 3 in-app purchases, starting at $1.99 per month and Markdown.md sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Chem Calc against 5.0 for Markdown.md. Both are backed by a comparable volume of ratings — 1 and 2 respectively.
