Intelligent Frost & Ice Prediction
Thank you to everyone for keeping FrostGuard in the Top #10! Hope you enjoy the new features.
FrostGuard tells you tonight whether frost will form by morning, so you know whether to cover your windscreen, take care on the roads or protect your plants.
Most weather apps only forecast the air. FrostGuard works out how cold the surface you care about will get: your windscreen, the road or path, or the grass. It looks at temperature, humidity, dew point, wind and cloud hour by hour, then gives a clear Low, Moderate or High risk.
Choose how you use it:
• Windscreen / Emergency Response: a clear car in the morning, with advice on covering the glass.
• Driving, Walking & Cycling: icy roads, paths and bike routes, including rain before a freeze.
• Gardening: ground frost and frozen soil, so tender plants and seedlings are protected in time.
Every forecast explains itself in plain words: how cold the air gets, how wind and cloud change the cooling, and why that adds up to your risk.
• A daily alert at the time you choose
• The next 48 hours on one graph, with tonight's and tomorrow night's lows
• Widgets for the Home Screen and Lock Screen
• Apple Watch app and complications
• CarPlay: tonight's risk and what to do, on your car's screen
• Nightstand mode: turn your iPhone on its side for a bedside frost clock
• Made for iPhone Duo, iPad and every iPhone
• Fine-tune mode: tell FrostGuard whether there was frost, and it learns your spot
• 12 languages, with °C or °F and mph or km/h from your iPhone's settings
Private by design: no account, no ads.
Made by a UK firefighter who needed a clear windscreen when called out on a frosty night.
