• Paediatric triage: complaints for patients under 17, with children's heart and breathing rates by age and the paediatric GCS in Quick reference. • Age groups: tap Adult (17 and over) or Child, then the child's age group: under 3 months, 3 months to 3 years, or over 3 years. Children's temperature rows match the age group, and the screen label shows it. • Simpler screens: at most two per complaint, vital signs then other findings, or one closest-match list. Every list runs most urgent first. • New complaint groups, arrests first, and a search that understands British spellings and bedside abbreviations. • Clearer result: "How this level was set" names the finding that set the level, or the complaint's starting level. • Every result now says which edition the app follows and that it supports, and does not replace, clinical judgment. • Plainer wording throughout.

Clarity improvements to the modifier screens, based on emergency physician feedback. - Vital sign findings are now grouped by dimension — Respiratory, Circulatory, Level of Consciousness, and Temperature — so you can scan one system at a time. - Options within each group are ordered mild to severe, matching how severity is usually read. - Pain screens now state the pain axis in plain language rather than CTAS terminology. The full CTAS term is retained in the breadcrumb and in "Why this level". - Pain options are grouped acute first, then chronic. - The Continue button now reads "No findings — continue" when nothing is selected, making it clear that recording no findings is a valid answer. - A new References section in About links to the official CTAS source documents this app's triage logic derives from. All CTAS acuity levels, encoded labels, and source citations are unchanged.
