# Learn ICU vs Q4uDoc

The clearest difference is ads: Learn ICU at none against Q4uDoc's shown. Learn ICU also leads on ratings volume (191 vs 3) and monetization model (free vs ad-supported). Q4uDoc's advantage is rating (5.0 vs 4.6) and update cadence (every 2 weeks vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Q4uDoc holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Learn ICU has 191 ratings behind it against 3, so its average is the more settled of the two.

Learn ICU ships an update every 4 months, Q4uDoc every 2 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
