====== Is it possible to Navigate with the App in the Background or the display turned off? ======

Yes, this was implemented in [[:changelog|Kurviger version 1.1.12]].

If you are using a different app and need to run it while locking the screen, have a look at the [[https://play.google.com/store/apps/details?id=biz.obake.team.touchprotector|Touch Protector App]]. This app allows you to lock your smartphone and even to create a black overlay to save energy (especially true for smartphones with OLED screens).
