SmartNavi emulates GPS with your movement.
reminds me of SmartNavi. I remember reading about that app a few years ago, but I've never actually tried it out.
or just allow smartnavi (https://play.google.com/store/apps/details?id=com.ilm.sandwich&hl=nl) to work. It works wonders for just navigating with google maps, Would only work on foot so driving or biking won't work. And people who walk on a treadmill should just go and walk in the fresh air outside anyway.
