This app has developed with love in Switzerland. No data is collected or shared. Support us with the price of a coffee! Thank you!!

Main features:
• Display of altitude (above sea level), accuracy (in meters or feet)
• No annoying ads
• No data is collected or shared
• Warning for inaccurate signal

Additional features:
• Display of coordinates and speed (in km/h or mph)
• Aircraft mode display: Altimeter in aviation design (always displayed in feet)
• Comparison of the current altitude with known buildings or mountains (Matterhorn, Mount Everest, ...)

Please note:
The measurement is conducted via GPS / Galileo / Glonass satellites. The accuracy can be affected by walls, roofs, tall buildings or trees and bad weather. For best results, the measurement should be done outdoors. Because the location of the satellites can take a few moments, the accuracy increases with time.
