# EOTC Bible vs CISI IOC Prep

EOTC Bible and CISI IOC Prep are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support 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. EOTC Bible sells 1 in-app purchase, starting at $3.99 per month and CISI IOC Prep sells 3 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
