# Exam SC vs CDL Quest

The clearest difference is update cadence: CDL Quest at every 2 days against Exam SC's every 12 months. Exam SC's advantage is iOS requirement (10.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Exam SC sells 1 one-off in-app purchase and CDL Quest sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Exam SC ships an update every 12 months, CDL Quest every 2 days. The most recent releases landed on October 25, 2026 and October 17, 2026 respectively.
