# Compendium Medicine vs Oncourse AI

The clearest difference is ads: Compendium Medicine at none against Oncourse AI's shown. Compendium Medicine also leads on rating (5.0 vs 4.8). Oncourse AI's advantage is ratings volume (448 vs 1) and iOS requirement (16.4 vs 18.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Compendium Medicine sells 6 in-app purchases, starting at $3.99 per month and Oncourse AI sells 10 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Compendium Medicine holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Oncourse AI has 448 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
