Flynex

Flynex is the offline-first electronic flight bag designed for private and general aviation pilots. Everything about your aircraft — tail number, powerplant specs, avionics, weight and balance envelope, and POH performance tables — lives in one place, always available without a network connection.

Plan every flight with real numbers. Flynex checks weight-and-balance compliance against your actual CG envelope, interpolates takeoff and landing performance directly from your POH data, and computes a full fuel plan with reserves. Every result comes back green, caution, or red — so you know before you go.

Stay ahead of airworthiness. The Maintain tab tracks inspections, Airworthiness Directives, oil changes, component overhauls, and open squawks — each with calendar and hours-based intervals. Start instantly with the built-in FAR Part 91 regulatory set (annual, transponder, pitot-static, ELT, VOR check), or add your own custom items. The Documents vault stores camera photos of your ARROW paperwork with expiry dates that flow directly into the Aircraft Readiness panel.

No account. No cloud. No subscription. Flynex runs entirely on-device — dark-themed, fast, and precision-focused for the pilot who demands the same standard from their tools as from their aircraft.
