Scores - Medical Calculator

About this app

Scores by Web of Medicine: 780+ clinical calculators in your pocket. No internet required. Every clinical score, formula and decision rule you reach for on rounds, in one app, fully offline, with the original validation paper cited inside each tool. Built for the way you actually work: at the bedside, in the ED, on call at 3 a.m., or in the basement of the hospital where Wi-Fi gives up. Scores loads instantly, runs offline, and gets out of your way. NEW: A CLINICAL CASE EVERY MORNING A short clinical vignette arrives each day. Read it, decide which score answers it, then tap through — the calculator opens already filled in with the case, so you go from question to an interpreted result in seconds. Cases are matched to the specialty you choose, and you can read each day's case in the app whether or not you allow notifications. WHAT'S INSIDE • 780+ calculators across 43 specialties • Every score with its thresholds, risk interpretation and source citation • Three scoring engines: sum-based scales, formula-based equations, conditional decision rules • Search by name, abbreviation or fragment ("creatinine clearance" finds CrCl) • Favourites: pin the handful of tools you actually use to the top • True dark mode: easy on tired eyes, easy on battery • No internet required, ever.

WHY OFFLINE MATTERS Hospital Wi-Fi is unreliable. ED basements have no signal. Patients cannot wait while a website spins. Scores lives entirely on your device: every formula, every threshold, every reference bundled at install. FREE AND PREMIUM A selection of calculators is free to everyone, with no account. Sign in with your email and the entire library unlocks free for one month. After that, a single one-time purchase keeps everything unlocked for good — no subscription, ever.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
