WatchVario is a navigation tool for glider pilots that provides a backup source for altitude and vertical speed data. It utilizes internal sensors and Kalman filtering to deliver real-time flight metrics through an intuitive interface designed for quick information acquisition. ## Key Features - **Sensor Fusion Altitude**: Calculates altitude in feet above mean sea level by fusing GPS data with internal pressure sensor readings. - **Uncompensated Variometer**: Displays actual rate of climb or descent in knots using Kalman filtering to smooth the output. - **Human-Centric Interface**: Features a simple layout with both analog and digital displays to minimize pilot cognitive load. - **Demo Mode**: Provides a ground-based simulation mode to allow users to test the interface without flight data. ## Who is it for? Glider pilots of all skill levels seeking a secondary cockpit instrumentation backup. ## Links - [App Store](https://apps.apple.com/us/app/watchvario/id1668552156?uo=4) - [Full Intelligence Report](https://marlvel.ai/apps/watchvario) --- *This is an overview report.
