About

Rounding Errors

Features
Read full description

Confidence is cheap. Judgment isn't. Rounding Errors is a two-minute daily round for clinicians. Dr. AI gives a confident, plausible answer to a real clinical question — and your job is to add the human read it missed: the safety catch, the patient's story, the question you'd ask first, the thing it didn't consider. It's not a quiz and there's no score. It's a daily habit for the judgment that AI can't reproduce — and a growing record of what you noticed. How a round works • Read Dr. AI's answer — clean, confident, and often incomplete. • Add your read through one of five clinical lenses. • See Dr. AI reflect on its own answer, then log your judgment. • Tap Reflect to continue in Learner+ for reflective CME/CE credit. Features • Daily Rounds — one fresh case a day, plus topics drawn from your week. • Create a Round — start from any topic or question you're thinking about. • On-device Dr. AI — powered by Apple Intelligence; your notes never leave your phone. • Your Judgment Chart — a Discernment Fingerprint showing the lenses you reach for, and the ones you don't. • Challenge Dr. Super Smart AI — optionally pit your read against a frontier model on a single round. Private by design. Your written note stays on your device. Only a generalized question is ever used to generate an answer — never your note. Reflective CME/CE credit is delivered by Learner+, a separate service. Rounding Errors is for clinical education only — not medical advice, and not for emergencies or clinical care decisions.
