Real Altimeter

"Real Altimeter" is a mobile application that transforms your smartphone into a functional aircraft altimeter, featuring an adjustable Kollsman window, altitude measurement in metres or feet, and pressure readings in various units. Designed for devices with built-in barometric sensors, this app provides an educational tool for aviation enthusiasts, though it's important to note it should not replace certified instruments and won't function in pressurized cabins.
