# DevPrep vs InterviewGenie

The clearest difference is update cadence: DevPrep at every 2 days against InterviewGenie's every 5 months. DevPrep also leads on iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DevPrep sells 5 one-off in-app purchases and InterviewGenie sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DevPrep ships an update every 2 days, InterviewGenie every 5 months. The most recent releases landed on September 24, 2026 and September 14, 2026 respectively.
