# Sterile Processing CRCST vs CRCST Exam

The clearest difference is iOS requirement: Sterile Processing CRCST at 13.0 against CRCST Exam's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sterile Processing CRCST sells 4 in-app purchases, starting at $6.99 per 7 days and CRCST Exam sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
