around you.

What it does
One app across phone, watch and web.

Alerts where it matters
Opt in to be notified when you enter a hazard zone, plus severe-weather and air-quality warnings for your area.
Works offline
The full hazard database ships with the app, so it keeps working with no signal — exactly where you need it.
On your wrist
Companion apps for Wear OS and Apple Watch show nearby hazards without reaching for your phone.
Eight languages
English, German, French, Spanish, Italian, Portuguese, Russian and Danish.
