What's New in DrugDoses

7.0

November 6, 2026

DrugDoses 7.0 is a complete redesign, built for the latest iPhone and iPad. • A fresh new look: cleaner pages, larger headings and easy-to-read cards, designed for iOS 26. Dark Mode is fully supported. • Two new PedCalc calculators: SpO₂/FiO₂ ratio (S/F) and Oxygen Saturation Index (OSI), with PALICC-2 thresholds to help you assess oxygenation when no arterial blood gas is available. • Faster CodeBlue: edit your pre-set doses from the top of the screen, save them with a single tap, and enter decimal weights such as 10.7 kg. On iPad, CodeBlue now works just like on iPhone. • Easier input: enter FiO₂ as 60 or 0.60, a newborn's weight for ETT sizes in kg or grams, and height for BMI in feet and inches. Decimals follow your region, with a comma or a point. • Notes at a glance: the note button now shows whether an entry already has one of your notes. • Better search: type "SpO2" or "FiO2" to find the new calculators. • Up-to-date content: the latest Drug Doses dataset, with Frank Shann's most recent corrections. • New in Settings: "About the authors", the story of Frank Shann, Oliver Karam and DrugDoses since 2002. • Plus a redesigned iPad menu and many smaller fixes and improvements. Your favorites, notes and Dropbox sync carry over automatically. Thank you for all your feedback over the years: it shapes every update. If DrugDoses helps you at the bedside, a review on the App Store helps other clinicians find it.
