Description by Medicon Apps(from the App Store)
DDx is a fast, offline differential diagnosis lookup tool — like a textbook in your pocket. Open any symptom and see a ranked list of diagnoses, with don't-miss conditions surfaced first.
Built for medical students, residents, and clinicians who want a no-frills educational reference at the bedside. In the same category as Diagnosaurus.
WHAT'S INSIDE
• 375 symptoms across 17 body systems • 6,148 differentials, ranked by probability and urgency • Don't-miss diagnoses highlighted in red • ICD-10 codes for the most common conditions • Search by symptom name, synonym, ICD-10, or diagnosis • Generated PubMed search references on every diagnosis • Bookmark symptoms for quick recall
Unlock the workflow tools that keep you moving fast:
• Five clinical scoring calculators — HEART (chest pain risk), Wells (DVT pre-test probability), PERC (PE rule-out), CURB-65 (pneumonia severity), Modified Centor (strep pharyngitis) • Reverse condition lookup — find every symptom a diagnosis can present with • Patient-context filters — age and sex chips on every symptom • All future content and feature updates included
The core differential diagnosis lookup stays free, forever.
DESIGNED FOR THE BEDSIDE
• Built for iPhone and iPad with full Dark Mode — true near-black for dim wards • Triage-board layout: hairline rules, ranked numerals, urgency-only color • 100% offline after install — no account, no sign-up, no tracking, no ads • Universal app: one purchase covers iPhone, iPad, and Apple Vision Pro
