Off 2 is the flight tracker that keeps working when your wifi doesn't. While other apps lose signal the moment the cabin door closes, Off 2 uses your iPhone's GPS and barometer to track your flight in real time — at 35,000 feet, in airplane mode, over the ocean. No internet, no subscription, no excuses. — SCAN YOUR BOARDING PASS Tap your boarding pass barcode (QR, PDF417, Aztec, DataMatrix) and Off 2 fills everything in: airline, flight number, route, date, seat, booking reference. Boarding to wheels-up in seconds. — LIVE TRACKING, EVEN OFFLINE Watch your plane move on a stunning 3D globe — real position, real altitude, real ETA. The day-night terminator shows you exactly when you'll cross into sunrise. Flight progress that doesn't freeze. — SHARE YOUR FLIGHT Send a live link to family before takeoff. They watch your plane move across the globe in real time, see your ETA tick down, get notified on landing — even if you have no signal in the air. Peace of mind, no airline app needed. — APPLE WATCH COMPLICATION Time remaining, ETA, and progress right on your watch face. Updates autonomously, even when the iPhone app is closed. A glance is all it takes. — LIVE ACTIVITIES Your flight on the Lock Screen and Dynamic Island. No need to unlock or open the app. Just look down. — MULTI-SECTOR ITINERARIES Plan complex trips with multiple flights and stopovers. Edit times sector by sector — adjustments cascade forward automatically. Perfect for round-the-world routes, business travel, or any long-haul with a connection. — PEER CHAT AT 35,000 FEET Find other Off 2 passengers on your flight over Bluetooth and WiFi. No internet required. Share your seat, swap snacks, make a friend at altitude. — CURIOUS WHAT THE PILOTS SEE? UNLOCK PILOT MODE The cockpit view, in your seat. Barometric altimeter with QNH/QFE, Energy Path Angle (EPA) gauge, flight plan parsing, proper flight level display at cruise — plus flight replay on the 3D globe, external Bluetooth GPS receivers, custom offline maps, and the full aircraft performance database. One purchase, yours forever — no subscription. (In-app purchase.) — AIRCRAFT DATABASE Browse 200+ aircraft with photos, by category (airlines and business jets), manufacturer, and model. Full performance data included with Pilot Mode. — STUNNING 3D GLOBE Day-night visualization, your great circle route, tap to recenter on yourself. Optional: drop your own .mbtiles file into the Off 2 folder for custom maps. — PRIVACY FIRST No account. No tracking. No ads. Your flight data never leaves your phone unless you explicitly share it. — 39 LANGUAGES Fully translated for 39 App Store regions, including Arabic, Chinese (Simplified & Traditional), French, German, Hindi, Japanese, Korean, Portuguese, Russian, Spanish, Thai, and more. — HIGH-RESOLUTION GLOBE (PILOT MODE) Turn on the optional high-detail basemap and the world becomes four times sharper as you zoom in — coastlines, islands, terrain and night-time city lights. It downloads once, then works entirely offline like everything else. The flight tracker your last one wishes it was.
