About

Muster Defense builds field software that stays on your device. See the air around you. Keep a private record of what changed. We sell apps, not data. Veteran-owned. Not a government app.

The name comes from the Revolutionary call to muster — to assemble.

We are not a government app. We do not claim official status.
