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 โ€” 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 โ€” and a growing record of what you noticed. How a round works โ€ข Read Dr. AI's answer โ€” clean, confident, and often incomplete. โ€ข Add your read through one of five clinical lenses. โ€ข See Dr. AI reflect on its own answer, then log your judgment. โ€ข Tap Reflect to continue in Learner+ for reflective CME/CE credit. Features โ€ข Daily Rounds โ€” one fresh case a day, plus topics drawn from your week. โ€ข Create a Round โ€” start from any topic or question you're thinking about. โ€ข On-device Dr. AI โ€” powered by Apple Intelligence; your notes never leave your phone. โ€ข Your Judgment Chart โ€” a Discernment Fingerprint showing the lenses you reach for, and the ones you don't. โ€ข Challenge Dr. Super Smart AI โ€” 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 โ€” never your note. Reflective CME/CE credit is delivered by Learner+, a separate service. Rounding Errors is for clinical education only โ€” not medical advice, and not for emergencies or clinical care decisions.

Verdict

The call
