# AO Surgery Reference vs Vumedi

The clearest difference is rating: Vumedi at 4.9 against AO Surgery Reference's 4.4. Vumedi also leads on update cadence (every 9 days vs every 6 months) and ratings volume (4.3K vs 14). AO Surgery Reference's advantage is ads (none vs shown) and review sentiment (86% vs 66%). On price, 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.

Vumedi holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Vumedi has 4.3K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 86% of AO Surgery Reference's written reviews are positive against 66% of Vumedi's, so the app with the better star average is not the one people write more warmly about.

AO Surgery Reference ships an update every 6 months, Vumedi every 9 days. The most recent releases landed on September 18, 2026 and September 24, 2026 respectively.
