Both are free to download. CTCAE 5 Pro sells 2 in-app purchases, starting at $1.99 per month. OncoAir asks for nothing beyond the download.
CTCAE 5 Pro holds the better App Store score, 4.9 against 2.3. That said, the two scores are not equally well evidenced: CTCAE 5 Pro has 45 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 25% of OncoAir's written reviews are positive against 0% of CTCAE 5 Pro's, so the app with the better star average is not the one people write more warmly about.
OncoAir ships an update every 6 weeks, CTCAE 5 Pro every 5 weeks. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
