Set your route on the ground. Once you're in the air, pftracker uses nothing but your phone's GPS to show altitude, speed, heading, and ETA — even in airplane mode, at 35,000 feet.
This isn't on the Play Store, so it's a direct APK download. Your phone will ask you to allow installs from this source the first time — that's expected. After that, pftracker checks for and installs its own updates.
Pick your route before boarding — enter airports manually or look up your flight number. This is the only step that touches the network at all.
GPS keeps working in airplane mode. No wifi, no cell service — your position, altitude, and ETA update live on the map for the whole flight.
If the app closes by accident mid-flight, reopening it offers to resume the exact same session right where it left off.
Dark, minimal, built to be glanced at in a dim cabin — not read.
The map ships inside the app. No tiles to download, no server to reach, nothing that can fail to load at 35,000 feet.
Reads the phone's own pressure sensor where available, alongside GPS altitude, for a closer match to what the cockpit sees.
Enter departure and arrival airports manually, or look one up by flight number before you board.
Speed, heading, vertical speed, distance, elapsed time, local time at destination, raw coordinates — show only what you want.
An accidental swipe-away mid-flight doesn't lose your track — relaunching picks the same session back up.
No Play Store round-trip. pftracker checks its own GitHub releases and installs new builds on your say-so.
