altimeter professional vs Sensors Toolbox

The professional altimeter with automatic altitude detection that works even without an internet connection! With the professional altimeter app, you can find out the actual altitude of the place where you are. The app automatically displays the altitude using a complex algorithm that combines three measurement methods: * Through satellite triangulation (also works without an internet connection) * Through map altitude, retrieving the terrain elevation for your location * Through the pressure sensor (if available), calibrated using the nearest weather station Carefully designed from a graphical perspective, the app recreates an analog altimeter (in meters or feet) with a digital measurement display. Here are some of the features: * Automatic altitude measurement (with the option to manually select one of the three measurement methods: [Map Altitude, Flight Altitude, GPS Altitude]) * History function with route tracking on the map and elevation-change graphs [works even when the app is closed], with indicators for speed, average speed, and elevation gain * Photo gallery of your routes with data overlaid on the photos * Alert system for sending your location by message or SMS in case of need * Weather forecast with trend information, temperature, and humidity measurements * Photos with overlaid data, location, and altitude * Custom widget to add to your Home Screen With the additional Premium feature, you can: * Remove advertisements * Remove the branding from photos OPTIONAL SUBSCRIPTION Only if you want to, you can activate the Premium version to remove ads and the watermark from photos: 1 month, 6 months or 1 year. Payment will be charged to your Apple Account upon confirmation of purchase. The subscription automatically renews unless cancelled at least 24 hours before the end of the current period; you can manage or turn it off in your account settings.
