Frostbite Calculator is an easy-to-use reference tool that uses your location and local weather information to determine if frostbite conditions or hypothermia temperatures are imminent in the area. Frostbite is caused by prolonged skin exposure to cold weather, surfaces, or liquids.

The app does use any invasive advertising; however, there is a [Buy Warm Clothing] button available. As an Amazon Associate, the app creator may earn an affiliate commission for qualifying purchases.
