120Hz Native Performance
Written 100% in SwiftUI and Metal-accelerated MapKit. Zero sluggish web-view wrappers or cross-platform bottlenecks. Panning charts and streaming vector tiles feels instantaneous.
60 - 120 FPS PROMOTION
A modern, fluid, distraction-free Electronic Flight Bag
for aviation enthusiasts and pilots.
Built natively from scratch in SwiftUI with zero cockpit clutter, 120Hz ProMotion responsiveness, full offline terminal procedures, and open avionics hardware integration.

Engineering Focus
Designed for cockpit focus, not subscription bloat.
We stripped away the clunky menus, invasive tracking, and five-level navigation trees found in legacy aviation software to give you instant situational awareness.
In-Flight Route Token Parsing
Type naturally. Dotted and space-separated tokens automatically resolve into waypoints, victor airways, SIDs, STARs, and instrument approaches. Expand any airway chip into deletable sub-fixes with a tap.
ARINC 424 • CIFP RESOLUTIONLiquid Glass Ergonomics
Adopting Apple's latest Liquid Glass design language. Semi-translucent control surfaces provide critical heading, altitude, and ground-speed telemetry without obscuring the airspace beneath you.
APPLE HIG • COCKPIT DARKOpen Hardware Support
Direct plug-and-play interoperability with Stratux, GDL-90 Wi-Fi receivers, and external Dual / Garmin Bluetooth GPS pucks. Receive live ADS-B traffic and in-flight weather without proprietary hardware locks.
GDL-90 • STRATUX READYTotal Offline Readiness
One-tap downloads for sectional basemaps, FAA d-TPP approach plates, airport diagrams, and digital obstacle files. Built-in projected dead-reckoning keeps you oriented even in GPS shadow zones.
FAA AIS • 28-DAY AIRACZero Tracking & Local Storage
Your flight plans, kneeboard notes, and GPS coordinates remain strictly on your device. Zero telemetry SDKs, zero ad networks, and zero corporate data harvesting.
