Off 2
Your offline flight companion — 3D globe, real-time ETA, and day/night crossings without internet.
- Offline flight tracking on a 3D globe — no internet required at any point
- Real-time ETA, distance, and day/night crossing visualization
- Available on iPhone, iPad, Mac, Apple Vision Pro, and Apple Watch
Off 2 is a flight companion app built for pilots, frequent travelers, and aviation enthusiasts who want meaningful flight data without depending on connectivity. Whether you are crossing the Pacific or flying in and out of radar coverage, Off 2 gives you a live picture of your flight without touching the internet.
The 3D globe
The centerpiece of Off 2 is a high-quality 3D globe rendering your current position, route, and the live day/night terminator. Unlike map-based apps, the globe gives you the true geometry of your flight path — great circle routes look like great circles, not distorted arcs.
What Off 2 shows
- Position: Continuous GPS-based tracking updated in real time
- ETA and distance: Dynamic calculations as your flight progresses
- Day/night crossings: Real-time terminator with crossing time predictions
- Route visualization: See where you’ve been and where you’re going on the globe
Apple ecosystem
Off 2 runs natively across the Apple ecosystem:
- iPhone and iPad — full interactive globe experience
- Mac — native macOS app, same capabilities
- Apple Vision Pro — spatial computing interface
- Apple Watch — flight complications (ETA, distance) added in v1.6; aircraft WiFi integration added in v1.4
Who uses Off 2
Pilots who want a clear offline picture of their own flight. Frequent travelers curious about their route geometry. Anyone who wants real data rather than an airline’s entertainment screen map.
Frequently asked questions
Does Off 2 require an internet connection?
No. Off 2 is fully offline. All globe rendering, position tracking, ETA calculations, and day/night crossing display work without any network connection — ideal for long-haul flights with limited or no connectivity.
How does Off 2 track position without internet?
Off 2 uses the device's GPS receiver and onboard sensors. No external data source is needed.
Is Off 2 available on Apple Watch?
Yes. Version 1.6 added Apple Watch support with flight complications, so you can glance at ETA and distance without reaching for your phone.
What is the day/night crossing feature?
Off 2 renders the current day/night terminator line on the globe in real time, showing you exactly when your flight will cross from day into night or vice versa — useful for planning sleep and managing fatigue on long sectors.
