What's coming

Position, height, speed, arrival time in local time.

Downloaded before you board.

When the GPS drops out, with how sure it is.

Satellites, signal and what the app is doing.

Every flight, with export to a spreadsheet.

Whatever the closed test turns up comes first.

A one-off payment through Google Play: Unlimited £3.99, Pro £7.99 (£4.99 from Unlimited). Testers keep Pro free.

Tell us how your first flight went and get a second one free.

Which features are used and where the app struggles, with a switch to turn it off. Never your position, route or airports.

Once the test is done and Google approves.

Before take-off, fetch the airline's filed route, so the estimate follows the oceanic track instead of a straight line when the GPS drops out.

A small map and arrival time over a film or another app.

With internet before you board: the planes around you, and where your own aircraft is on its way in.

Your routes in Google Earth and mapping apps.

Arrival time and turbulence ahead on your wrist. Wear OS first.

Once the Android app is settled.

Zone lines, and the local time where you are now.

Watch the route back after you land.

Mark a point and add a note.

Send where you are when the plane has Wi-Fi.

Your recorded route against the aircraft's own broadcast track.

How bumpy your flight was, measured by the phone's motion sensor while it's still: a score after landing, where the bumps were along the route, and records in the logbook.

Only if it measurably improves it; in our tests the route mattered more.
