# Aeshna vs STP Viewer

The clearest difference is iOS requirement: STP Viewer at 13.0 against Aeshna's 18.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Aeshna sells 10 in-app purchases, starting at $4.99 per month and STP Viewer sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
