Is FlightDex free?
Yes. Tracking and logging flights, your flight status refreshed when you open the app from 24 hours before departure to landing, sharing a flight as a link, your full travel passport, importing your history, and on-device boarding passes are free forever, with no ads. Pro ($49.99/year, $7.99/month, or $3.99/week as a weekly plan for the weeks you travel, cancel anytime, with a 1-week free trial) adds continuous background tracking, live alerts, delay predictions, the live map, and airport boards.
How is FlightDex more private than other trackers?
You can use FlightDex without making an account at all. Boarding passes are encrypted on your phone, never uploaded, and deliberately left out of cloud backup. The app has no location permission at all — check its permission list on Google Play. The only things it ever asks you for are notifications, the camera and your calendar: to read it, if you import from it, and, from the next app update, to write your flights into it, only if you turn that on. There is no analytics SDK, no crash reporter and no advertising SDK in it.
Can I share a flight with someone who doesn't have the app?
Yes. A share link opens in any browser with the flight's status and how long ago it was updated, its route and the aircraft's last reported position, so the person meeting you needs no app and no account. The link carries no booking code, no seat and no full name — only a short display name if you set one — and you can see every link you've made and revoke it in a tap. Creating a share link, opening one, and following the flight in the app are all free.
Does it work offline?
Your flights and your boarding passes do, and a pass renders on the phone itself, so you can scan it at the gate on airport wifi that isn't cooperating. Your passport needs a connection.
What Android version do I need?
Android 8.0 or later. It runs on phones and foldables, with a home-screen widget and, with Pro, a live tracking notification while you fly.
