Fahrenheit Thermometer Plus is a free digital thermometer application available for iPhone users. Developed by SHIGETO TAKAGI, this app provides a convenient way to measure the ambient temperature of your current location using GPS.

With Fahrenheit Thermometer Plus, you can easily check the temperature in degrees Fahrenheit. The app also includes a conversion calculator that allows you to convert Fahrenheit to Celsius using a simple formula. The Fahrenheit temperature is indicated in the badge, with temperatures below zero represented as 1000 and temperatures above zero as 1005 degrees Fahrenheit.

One notable feature of this app is its barometric function, which utilizes the pressure sensor available on iPhone 6 and later models. This feature provides additional accuracy in measuring the outdoor temperature.

While Fahrenheit Thermometer Plus is primarily designed for outdoor temperature measurement, it can also serve as a reference for choosing appropriate clothing based on the weather conditions. The app also displays the sunrise and sunset times, adding to its utility.

Please note that some areas may be excluded from the temperature measurement due to limitations in GPS coverage.
