The Android version of the Loss of the Night app has been updated (new version is 2.1.5). The main changes with this update were to target the boundary between averted vision and not visible (it was incorrectly set to target the boundary between visible and averted in the last version), and to deal with the (rare) problem that some phones sometimes reported incorrect GPS positions.
The solution we introduced to solve the GPS problem may unfortunately prevent some phones from using the smoother gyroscope function that was introduced with the second version of the app. If you notice that the display of the stars seems jittery, try immediately quitting the star search and starting it again. If that doesn't work, please contact me to let me know what model of phone and which version of Android you are using. While we do not currently have funding to do further development, your input could help us figure it out more quickly in the case we do find additional funding.
