# CodeSnack IDE vs Async.dev

CodeSnack IDE's advantage is ratings volume (1.6K vs 2) and chart position (#174 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. CodeSnack IDE sells 12 in-app purchases, starting at $4.99 per month. Async.dev asks for nothing beyond the download.

Async.dev holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: CodeSnack IDE has 1.6K ratings behind it against 2, so its average is the more settled of the two.
