# ReviewNprep vs PSM I

The clearest difference is review sentiment: ReviewNprep at 50% against PSM I's 0%. ReviewNprep also leads on iOS requirement (12.0 vs 26.0). PSM I's advantage is update cadence (every 6 weeks vs every 18 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ReviewNprep sells 10 one-off in-app purchases and PSM I sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
