An Android app for visualizing FlySight GPS tracker data.


FloatSight need read and write storage permissions. (Saved tracks can be found on your mobiles storage in the FloatSight folder)

Open files directly from a FlySight -

  • Your Android device has to support USB-Host / USB On-The-Go.
  • You need an USB-OTG cable.

Other sources

Alternatively you can of course open and view Flysight tracks from any other storage location on your phone, attachments from messenger apps, downloads, etc.

Connecting to the FlySight

To connect your FlySight -

  • Connect your Android device with your FlySight using an OTG cable.
  • Change USB option (accessible via notifications bar) to "File transfer". (Give it a few seconds.)
  • Use the import function to open the track in FloatSight, a file picker is displayed and you will have to navigate to the USB mounted storage that is your FlySight and pick a track.
  • Use the load function to open imported tracks that are already on you mobile devices storage.
  • Don't Forget to properly eject your FlySight before disonnecting the cable. This is also done via the notification bar. (If no eject option is visible there, swipe down on the Android System notification for USB drive.)

Alternatively you can copy tracks from FlySight with any another file manager app if you prefer.

  • Either long tap on this yellow marker or tap on menu icon "[]" sets this as a range start/end.
  • The blue range marker averages and differentials of data within this range.
  • The scissors menu icon will crop the track to the current range.
