Ozrunways has saved my a$$ on several occasions, the worst being out the back of Bourke with crossing traffic at the wrong hemispheric level, and a constant bearing. Without it, I never would have seen it it time, there was no requirement for either of us to be broadcasting our radio position, both VFR OCTA. It was just that we were both using Ozrunways, both had mobile reception and both had traffic on that prevented a conflict. It’s a big sky out there until it isn’t. Another plane I fly has a raspberry pi ADSB receiver that shows traffic even without Ozrunways on my iPad. Best $100 ever spent.
