Litchi Mission on DJI Mini 4 Pro

That’s going to be a call that only the owner can make.

If one was an IOS user, they would have to get an Android flying device in addition to the drone. So with that added expense, they might consider going with the RC2 and living with the extra burden of manually converting and transferring their missions to the RC2.

If one already had an Android phone or tablet, it might be wiser to get an RC-N2 so that they could use Litchi seamlessly.

I have not checked to see if stand-alone RC-N2 controllers are readily available. That would allow you to grab that Mini Pro combo bundle and then pick up an extra controller.
