What this shows

Insulin on board (IOB) is how much of your Luna-delivered insulin is still active in your body. Seeing it can help you avoid stacking — taking more insulin on top of insulin that's still working.

Shows during an active Luna session, then carries the residual amount after the session ends until that insulin clears — e.g. 0.4 U.
Counts Luna-delivered insulin only — not insulin you deliver outside Luna.
This is information to help you decide. Luna won't recommend, change, or deliver a dose based on it.
