Apple Inc. has a moonshot-style project underway that dates back to the Steve Jobs era: noninvasive and continuous blood glucose monitoring.

The goal of this secret endeavor — dubbed E5 — is to measure how much glucose is in someone’s body without needing to prick the skin for blood. After hitting major milestones recently, the company now believes it could eventually bring glucose monitoring to market, according to people familiar with the effort.
