# DWSIM Simulator vs LabCodex

The clearest difference is iOS requirement: DWSIM Simulator at 12.0 against LabCodex's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DWSIM Simulator sells 10 one-off in-app purchases and LabCodex sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
