# PMI vs uCertifyPrep Security Basics

The clearest difference is update cadence: uCertifyPrep Security Basics at every 3 months against PMI's every 12 months. PMI's advantage is iOS requirement (10.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PMI sells 2 one-off in-app purchases and uCertifyPrep Security Basics sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PMI ships an update every 12 months, uCertifyPrep Security Basics every 3 months. The most recent releases landed on September 28, 2026 and October 13, 2026 respectively.
