Altimeter is a free application available for iPhone that serves as a handy tool for determining altitude with precision. Whether you're conquering a mountain peak or simply curious about your current altitude, Altimeter provides accurate readings in meters or feet. Additionally, the app allows users to save specific locations along their journey, making it easy to navigate back to those points later on. Compatible with iPhone, iPad, and Apple Watch, Altimeter offers a range of coordinate systems for location tracking, sharing options with friends, and customizable display modes.

One standout feature of Altimeter is its ability to utilize the GPS chip for altitude calculations without draining your device's battery excessively. The app ensures user privacy by only activating the GPS chip when the application is in use, with no background tracking. However, indoor use may limit GPS reception, affecting accuracy.
