iFly is not an ADSB receiver. You've always needed a separate device for ADSB-in to iFly. Yes, the iLevil device (either AW or AP) can replace whatever other ADSB receiver you had been using, but it doesn't replace your navigation app/charts/flight planning tool/ets. You still need something like iFly if you want your plane+autopilot to follow a magenta line/flight plan.
I don't know what plane you have, but the iLevil AP autopilot is not approved for certificated aircraft, only Light Sport and Experimental. Again, though, neither iLevil's autopilot product nor its panel displays include the full functionality of an EFB app like iFly. You still need an app like iFly to build your flight plan and send the commands to the autopilot to tell it where to go. That's why Levil has this page:
Unleash the power of your iPhone and iPad inside the cockpit! Our devices provide a complete wireless glass cockpit solution designed to improve your inflight situational awareness, flight experience, and comfort at a fraction of the cost.

The first app listed is the "Levil Aviation App", but it's not a replacement for a full EFB like iFly. Note this description, which says, "...while using your preferred navigation app." You're still going to need iFly, or something like it.
