# PE1 Exam Pro vs 433A MillwrightPrepApp

The clearest difference is device support: PE1 Exam Pro at 3 against 433A MillwrightPrepApp's 1. PE1 Exam Pro also leads on iOS requirement (14.0 vs 16.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. PE1 Exam Pro sells 10 in-app purchases, starting at $39.99 per month and 433A MillwrightPrepApp sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
