Wingbook · Friends beta

Thanks for testing.

Wingbook runs as a closed test on Google Play. You need an Android phone running Android 10 or later and a Google account. It takes a few minutes. The app is currently in German only.

How to join

  1. Request access

    Tap “Request access” above. A prepared email opens. Add the address of the Google account you use in the Play Store and send it.

  2. Open the test link

    Once I have added you, you get a link. Open it on your phone with the same Google account and tap “Become a tester”.

  3. Install

    The link takes you to Wingbook on Google Play. Tap “Install”. If the app does not show up yet, wait a few minutes and try again.

  4. First launch

    Allow notifications so reminders for reserve, glider check and backups work.

  5. Import flights

    Share an .igc file from your vario app or file manager and pick Wingbook. Or use the import in the app to select several files at once.

Please stick around

Before Wingbook can go public on Google Play, Google requires at least 12 people to keep it in testing for 14 days in a row. Please stay a tester for at least two weeks and do not uninstall the app during that time. Updates arrive automatically through the Play Store.

Never uninstall without a backup

Your flights live only on your phone. Uninstalling deletes them. Make regular backups under Mehr → Backup, ideally straight to Google Drive. If you already have Wingbook as a file (APK) from me, let me know before installing from the Play Store.

Feedback

The easiest way is in the app under Hilfe → Feedback. It reaches me directly, along with your device model and app version. You can optionally attach a picture and the last crash report. Or email contact@extralapstudio.com.

Especially helpful:

  • Does importing from your vario or XCTrack work?
  • Do distances and triangles roughly match XContest or the software you used before?
  • Did the app crash or freeze? What did you do right before?
  • What did you look for and not find?

Known issues

None reported yet. I will add them here as they come up.
