The Gear S3′s altimeter will constantly measure altitude and show it in meter/mile on the display. It’s also going to display an altitude graph with hour and altitude being plotted on the X-axis and Y-axis respectively. Users will be able to calibrate the altimeter with a single tap provided that the Gear S3 is connected to the internet and they turn on location services.
The barometer will measure atmospheric pressure which comes in handy when forecasting weather and determining altitude, readings will be displayed on the Gear S3 with the correct “hPa” unit. It will feature a weather indicator as well enabling users to quickly check on upcoming weather conditions. Users will be able to manually calibrate the barometer by setting reference values for altitude, sea level pressure and distance. The sudden weather changes warning will be on by default and it will warn users if a pressure drop of 4 hPa or more occurs in a 3-hour period.
