Education
Free · Designed for iPad. Not verified for macOS.
MedLex puts a complete medical dictionary in your pocket — clear definitions, real pronunciations, and the clinical detail you need, whether you're a nursing/med student, healthcare professional, or just trying to understand a diagnosis.
Look Up Any Term, Instantly
Browse the full dictionary with a fast A–Z index, or filter by category to find exactly what you need. Every term includes both a simple, plain-language definition and a full academic/clinical definition — switch between them with one tap.
Go Beyond the Definition
Term entries include causes, symptoms, treatment, and differential diagnoses, plus a zoomable medical illustration so you can study the detail that matters.
Hear It, Not Just Read It
Tap to hear the correct pronunciation of any medical term — no more guessing how it's said.
Search That Learns With You
Full search with trending terms and your recent search history, so the terms you look up most are always one tap away.
Save What Matters
Bookmark terms to your Saved list and revisit them anytime. Your Recently Viewed history keeps track automatically.
Daily Term
Build your vocabulary passively with a new featured term on your home screen every day.
Works On Your Terms
Sign in with Google or continue as a guest — your choice. Previously loaded terms stay available even without a live connection.
Available in English and Arabic.
