# OnePrep vs PrepifyMe

PrepifyMe also leads on in-app purchases (none vs 23) and ads (none vs shown). OnePrep's advantage is ratings volume (378 vs 10). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. OnePrep sells 23 in-app purchases, starting at $28.49 per 7 days. PrepifyMe asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for OnePrep against 4.6 for PrepifyMe. That said, the two scores are not equally well evidenced: OnePrep has 378 ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 45% of OnePrep's written reviews are positive against 100% of PrepifyMe's.
