# DermEngine vs Top Derm

The clearest difference is rating: Top Derm at 4.5 against DermEngine's 3.8. Top Derm also leads on ratings volume (59 vs 11). DermEngine's advantage is ads (none vs shown) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Top Derm holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Top Derm has 59 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 68% of DermEngine's written reviews are positive against 60% of Top Derm's, so the app with the better star average is not the one people write more warmly about.

DermEngine ships an update monthly, Top Derm every 6 weeks. The most recent releases landed on September 30, 2026 and October 9, 2026 respectively.
