# UpToDate vs IV Infusion Calculator

The clearest difference is in-app purchases: UpToDate at none against IV Infusion Calculator's 1. UpToDate also leads on rating (3.6 vs 3.3) and chart position (#206 vs unranked). IV Infusion Calculator's advantage is review sentiment (63% vs 28%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. IV Infusion Calculator sells 1 one-off in-app purchase. UpToDate asks for nothing beyond the download.

UpToDate holds the better App Store score, 3.6 against 3.3. That said, the two scores are not equally well evidenced: UpToDate has 586 ratings behind it against 74, so its average is the more settled of the two. Written reviews complicate that: 28% of UpToDate's written reviews are positive against 63% of IV Infusion Calculator's, so the app with the better star average is not the one people write more warmly about.

UpToDate ships an update every 5 weeks, IV Infusion Calculator every 2 months. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
