How it works

The algorithm behind Luna

Luna Eclipse® is the algorithm inside Luna. It’s designed to do the math and the hard work overnight, so you can spend more of your time thinking about things other than diabetes.

Small steps through the night

Every few minutes, Luna Eclipse® looks at your latest CGM readings and where they’re heading. It uses that information to decide whether you need insulin and how much to give. Luna then delivers small boluses in increments as small as 0.1 units.

One setting, once

There are no basal rates, carb ratios, or correction factors to set. Luna Eclipse® asks for one setting, which you enter during setup, and it works out the rest. Each night, it learns about you and personalizes settings to your individual needs.

Designed to help avoid overnight lows

HypoShield™ is a Luna Eclipse® feature designed to help reduce the chance of overnight lows by learning your diabetes profile and helping you adjust your settings.

When CGM readings stop, insulin delivery stops

If your CGM loses its connection, Luna stops delivering insulin until readings resume. Your basal insulin, which you take as usual, is not affected.
