Dictate or paste the start times. Military or 12-hour, mixed freely — the times only ever go forwards, which is enough to sort out the rest.
Runs entirely on this device — times only, no names, nothing leaves the phone. It cannot alert you in the background. A web page can't wake itself on iOS, so ClinicFlow is silent by design: the screen is the whole alert. It stays awake while you're with a patient.
