# IMAIOS e vs Prepry

The clearest difference is review sentiment: Prepry at 89% against IMAIOS e's 48%. IMAIOS e's advantage is monetization model (free with in-app purchases vs subscription) and rating (4.9 vs 4.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. IMAIOS e sells 2 in-app purchases, starting at $21.99 per month and Prepry sells 5 in-app purchases, starting at $49.99 per month. Whichever you choose, the download price is not the number that matters.

IMAIOS e holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: IMAIOS e has 1.4K ratings behind it against 251, so its average is the more settled of the two. Written reviews complicate that: 48% of IMAIOS e's written reviews are positive against 89% of Prepry's, so the app with the better star average is not the one people write more warmly about.

IMAIOS e ships an update every 9 days, Prepry fortnightly. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
