iVariometer is an altitude-change detection tool designed for aviation enthusiasts and paragliding or glider pilots. It uses the iPhone's barometric sensor to monitor vertical speed and climb or descent rate in real time, providing audible and visual cues about current trends. Its simple interface and responsive performance make it useful in demanding weather conditions, while its compact design suits outdoor flight scenarios where precise altitude-change information is helpful.
