- 📦DrugDoses updated to version 7.0DrugDoses 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.
