## What is FrostGuard?

Designed by a UK firefighter, this app is useful for those who need a quick and safe start to the day, or for those who simply know when the frost is coming!

What it does: 
Shows a simple frost-risk rating based on your location, prompting you to either cover your windscreen or not. For gardeners, cover your plants!
Notifications daily with a heads up on forecast.
Widgets - add frostguard to your home or lock screen for quick access!

Uses temperature, humidity/dew point, wind & cloud cover to predict glass frost formation.
Daily notifications to give you a heads-up to cover and protect your windscreen if need be.
Updates quickly when you open the app or pull to refresh.
Private by design: no account, no ads, no nonsense.

How it works:
On clear, still nights, glass can cool below the air temperature. FrostGuard estimates cooling and flags when ice is likely—so you know when to cover up the night before.

Who it helps:
Anyone with a car, motorbike or garden!
Emergency responders & shift workers: retained firefighters, ambulance staff, police, carers
Rural & on-call professionals: farmers, vets, midwives, trades on early call-outs
Transport & fleets: HGV/LGV, delivery drivers, taxi/ride-hail, depots, ground crews
Everyday drivers: commuters and school-run parents, gardeners, landscapers
Hobbyists: Stargazers and Anglers and cold dippers!
