XC FLY, from DAC Inc., is a flight computer and navigation app that converts a smartphone into an in-flight instrument for paragliding, hang gliding, and paramotor pilots. The tool supplies live instrument readouts, route navigation, recording and position sharing tailored for outdoor use. Key attributes include high-visibility cockpit visuals, offline aeronautical data, live tracking and an integrated digital logbook. It targets students through experienced cross-country pilots who want phone-based flight tools and community features.

What can the app do in real free-flight scenarios?

The app acts as a portable flight instrument by showing climb rate, ground speed and altitude on a glare-optimized cockpit screen, so pilots can read key data in bright conditions. It also offers a thermal assistant and wind estimator to support lift finding during flights. That orientation toward in-flight situational awareness reflects its design as a pilot-facing instrument rather than a passive mapping viewer.

How precise are the app's instruments and recordings?

The app provides a variometer, GPS speed, altitude and compass readouts and performs automatic flight recording with takeoff and landing detection, which supports reliable post-flight review. Flight logs export in the IGC track format for external analysis, and the logbook includes 3D replay plus statistics. Those capabilities make it suitable where recorded track integrity matters, such as cross-country validation and debriefing.

How does the app connect to sensors and handle maps?

The app runs on mobile hardware with built-in GPS and can be enhanced by external Bluetooth variometers to improve sensor precision. It includes offline aeronautical maps that show airspace boundaries, obstacles and waypoints, allowing navigation without a cellular connection. The connection model relies on standard device GPS and Bluetooth accessories, which keeps integration straightforward for pilots carrying an external variometer.

Who should use the app and what limits should they note?

The app targets free-flight enthusiasts from students to experienced XC competitors and adds a social layer with live position sharing, pilot profiles, groups and a community feed for flight sharing. Users are responsible for ensuring their use complies with local airspace rules and platform terms, and pilots who need certified instruments for competition should confirm acceptance before relying on phone-based readings.

A practical choice for pilots who want phone-based instrumentation and social flight tools

By combining in-flight instruments, recorded tracks and pilot-to-pilot sharing, the app serves pilots who accept a mobile-device workflow and community features. Its pilot-led design and positive user commentary on interface and recording reliability make it a solid option for sport and cross-country flying. Pilots should verify device GPS performance and local airspace rules before using it as a primary instrument.
