If you don't have access to an appropriate device, you can also print out a chart which shows the stars of Orion at different magnitudes. Then report the faintest magnitude visible through their web portal. This is best done when there's no moon, but if you're in an often-cloudy area, do what you can!

Dark Sky Meter is an iOS-only* app for doing quick/dirty sky-luminance ratings. I pull over sometimes when driving at night to grab a quick value somewhere I don't go often (and can't stop for 20mins to do a proper observation).

* The camera has to be categorised, which is impracticable for '000s of Android devices, but achievable on the smaller # of iOS devices.

Loss of the Night for iOS & Android walks you around the sky from brightest to faintest stars to establish what's the dimmest thing you can see. Needs half an hour putting aside as you need to let your eyes dark-adjust for a fair reading

We're losing our stars to light pollution.

Do your bit and submit light-pollution measurements from home. Even just one measurement is useful, though one a month would be amazing.
