Off 2 v1.4 is a major update that brings aircraft WiFi integration, an Apple Watch companion app, and smarter position tracking to your flight companion.
Aircraft WiFi Integration
Off 2 now reads position data directly from the aircraft’s flight management system when you’re connected to onboard WiFi. No configuration needed — just connect to the cabin WiFi and Off 2 detects the source automatically.
Supported systems:
- Air France — Onboard, Connect, and Freewifi networks
- Viasat — Used by many US and international carriers
- Panasonic Avionics — With bonus meteorological data (headwind/tailwind, OAT, wind direction)
This gives you FMS-computed distance remaining, ground speed, and time to destination — more accurate than GPS because it follows actual airways rather than great circles. When both GPS and WiFi data are available, Off 2 intelligently combines them and saves battery by throttling GPS updates.
Apple Watch Companion
The new Apple Watch app brings Off 2 to your wrist with quick message buttons for crew communication. Send pre-defined cabin status messages — ARM, TKO, TRB, COF, 100, LDG, DIS — directly from Apple Watch via the peer-to-peer network. Perfect for cabin crew coordination without pulling out your phone.
Smarter Position Tracking
Under the hood, Off 2 v1.4 completely rethinks how it computes speed and time to destination from WiFi sources. A sliding-window linear regression replaces the old two-point speed calculation, delivering much smoother ground speed readouts and more reliable ETA predictions — especially during doglegs and holding patterns.
Position source indicators now show live staleness states: teal for active WiFi data, degrading to orange (>30s) and red (>60s) when data goes stale. A subtle pulse animation on the source icon confirms data is flowing.
Other improvements
- GPS freeze detection — Detects when cached GPS data hasn’t moved in 120+ seconds at altitude, preventing stale position data from poisoning calculations
- GPS watchdog — Automatic recovery with exponential backoff when GPS updates stop arriving
- MPC peer improvements — Persistent unique peer IDs, deterministic tie-breaking, and periodic rediscovery prevent silent connection failures
- Live Activity throttle — Foreground updates limited to 10-second intervals to prevent iOS from disabling the Live Activity
- WhirlyGlobe rendering — Faster tile loading and better caching for smoother globe manipulation
Off 2 is available on iPhone, iPad, Mac, Apple Watch, and Apple Vision Pro — $3.99 on the App Store.
