A small sensor that watches over your health at home. Built with environmental-health experts, Leo detects what's harming you, directs the fix, and verifies your home is safe again.
Think Oura ring, for your home.
Early access · Short, occasional updates · No spam
Air quality monitors hand you charts and leave. Leo closes the loop — the way a doctor would.
Leo senses the invisible — humidity drift, VOCs, particulates, CO₂, and the exact conditions where mold takes hold — room by room, around the clock.
No charts to decode. Leo tells you what's wrong, where it's coming from, and the precise fix — do it yourself, or hand it to the right pro.
After the repair, Leo keeps watching until your air truly recovers — and tells you when your home has earned your trust back.
My home made me sick. Months of symptoms no doctor could explain — and the answer was mold, hidden in the walls the whole time. Leo exists so you and the people you love never have to worry about your home making you sick.
Join the list — be first when Leo ships, and follow the build as it happens.
