Insulin on board
Insulin on board
Off
When on, your Home screen shows how much of your Luna-delivered insulin is still active — so you can avoid stacking a dose on top of insulin that's still working. Off by default.
What it shows
Luna-delivered insulin only
Counts the insulin Luna delivered overnight — not insulin you take outside Luna.
During and after a session
Shows while a session is active, then the residual amount after it ends until that insulin clears — e.g. 0.4 U.
Information, not instruction
It's there to help you decide. Luna won't recommend, change, or deliver a dose based on it.
