SmartThermo

Smart Thermometer is a simple app to use the temperature sensors in your phone to show the temperature near your phone. With a beautiful design and great precision, this will be your default way of checking temperature instantly!

Please make sure your phone has a temperature sensor, otherwise this app can only show you temperatures from web services like any other weather app

Use of internet connection is optional, and internet + gps are only required for devices not having an integrated temperature sensor.

This app offers an upgrade package which adds charts with historical data of your phone's readings plus better widgets.

Designed with Full HD in mind, so it's a perfect match for the Galaxy S4 and all other phones, but will work on any other device as well, provided GPS and an internet connection is available

Permissions breakdown:

INTERNET - required for uploading data, and getting stats in return

GPS - optional for associating the temperatures with a location, and required for getting temperature data on devices which don't have a temperature sensor
