Alti-Barometer is a stand-alone Apple Watch app that uses your watch's barometric pressure sensor to track your altitude or weather-related barometric pressure changes. The app doesn't need an Internet connection, and is the perfect companion for back-country trips. While on your wrist, Alti-Barometer will keep a log of your altitude or barometric conditions, and keep you updated using your watch's main display to show weather conditions, altitude, or climb rate at a glance. Did you ever wonder just how fast that elevator was going? Or what the weather was going to be when camping? Or just how much under sea level that tunnel was? Alti-Barometer has your answer.
