Question on Walkera App Support

For those of you with a Voyager 4, I'm considering the purchase, but have been told that I should avoid the V4 because the phone/tablet app is not being updated. For me, as long as it doesn't crash and has no major bugs, I don't really need an update. For those of you who own this quad, have you noticed any kind of need for Walkera to update or upgrade the phone/tablet app, or is it just fine and functions as it is?

Any other input for my decision?

Thanks!
