- Best for
- Any clinician who needs a validated score at the bedside. Roughly 700 calculators, each with the original paper, the creator's own commentary and the caveats that decide whether the score applies — and it works with no signal.
- Limitation
- Deliberately single-purpose: it computes scores and does not answer questions, draft notes or reason about a case, which is why it scores 5 out of 10 on clinical scope despite being the best app on this page at its own job.
- Price
- Free; optional CME subscription
Dimension-by-dimension rubric criteria for iOS apps for doctors
- Clinical scope & reasoning5/10
Category high: 10/10
How 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.
- iPhone & iPad experience8/10
Category high: 9/10
Whether 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.
- Apple platform integration8/10
Category high: 8/10
Use 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.
- Offline & on-device privacy9/10
Category high: 9/10
What 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.
- Access & eligibility10/10
Category high: 10/10
Who 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.
