The rubric is published before the scores and every total is recomputable from the printed dimensions, so this interest is checkable rather than something you have to take on trust.

Epocrates and UpToDate Expert AI, dimension by dimension

Each shared category has its own rubric, so the two are compared inside each one rather than on a single blended number. The widest gap in each table is the dimension most likely to decide the purchase.

32 – 36UpToDate Expert AI by 4

iOS apps for doctors rubric, ordered by the size of the gap. Each dimension is scored out of 10.
Dimension	Epocrates	UpToDate Expert AI	Gap
Clinical scope & reasoningHow much of the clinical job the app does, and whether it reasons or only retrieves. A single-purpose reference scores lower here than a tool that carries a case from question to differential to note, regardless of how good it is at its one job.	4	7	-3
Access & eligibilityWho can actually install and use it, weighted as heavily as what it costs: App Store and in-app subscription price, the size of the free tier, and the gates in front of it — clinician-verification requirements, country availability and language coverage. An app that is free but closed to most of the world's clinicians scores below a paid app anyone can buy.	6	3	+3
iPhone & iPad experienceWhether the iPad build is a real tablet layout rather than a stretched phone app: multi-column reading, Split View and Stage Manager behaviour, one-handed iPhone reach, and typography you can read at arm's length on a ward round.	7	9	-2
Apple platform integrationUse of what iOS actually offers: on-device dictation quality, Shortcuts and widgets, Handoff between iPhone and Mac, Apple Watch presence, Face ID locking and Universal Search.	7	8	-1
Offline & on-device privacyWhat still works in a basement reading room with no signal, how much content is stored locally, and whether protected health information stays on the device or is discarded after processing.	8	9	-1

Epocrates

Best for: Fast prescribing checks: monographs, an interaction checker across multiple drugs, pill identification by imprint and colour, and formulary coverage — the reason it sits on more than a million clinicians' phones.
Limitation: Drug information only: no clinical reasoning, no differential, no documentation. The free tier is open to any clinician, but the deeper content and the US-centric formulary data sit behind the premium upgrade, which is why it scores 6 out of 10 on access.
Price: Free tier; premium around $175/year

UpToDate Expert AI

Best for: Clinicians who read long-form on an iPad and want expert-authored topics, graphics, mobile calculators, CME tracked as they search, and topic downloads that survive a dead zone. The separate Expert AI app adds conversational retrieval on iOS 26 and above, including visionOS.
Limitation: The most expensive option here by a wide margin, at 3 out of 10 on access, and the AI layer is a separate subscription on top. It retrieves curated content rather than reasoning about your case.
Price: Individual subscription around $559/year; Expert AI extra

Limits

What this comparison cannot tell you

Neither tool has been benchmarked here against live patient data. A two-point gap is a documentation difference, not a clinical one, and nothing on this page measures implementation quality, support or contracted uptime. This rubric scores the iOS build specifically, so an app with a weaker iPhone experience can rank below a lesser product with a better one; scores are not transferable to the same vendor's web or Android version, which we score separately. Access is scored as eligibility and not only as price, which means an app that costs nothing but admits only verified US clinicians ranks below a paid app any clinician can buy — a US physician who clears that gate should re-rank by the other four dimensions, where Doximity scores 8, 8, 8 and 6. Clinical scope is weighted heavily, which penalises excellent single-purpose apps — MDCalc and Epocrates are both stronger at their one job than their totals suggest, and a reader who wants only a calculator should read MDCalc as the winner. App Store pricing, iOS version requirements and feature availability change without notice; verify current terms in the App Store listing. No app here is a diagnostic device, and none replaces your institution's EHR companion app for chart access.

Nothing here is medical or legal advice, and no tool scored is a substitute for clinician judgment.
