I've had the Spark for a couple of weeks.  It's my first drone and I am really loving it.

This past weekend, I spent $20 bucks on the 3D FPV app in the iPhone App Store.  I already had a vr headset that I bought on Amazon 6 months ago, (I got the 'Homido 1' for 50 bucks.  Totally worth it even apart from the drone connection.  It has 3 separate eye cups, for if you are 1 normal, 2 near or 3 far sighted.)

I fired up the Spark and the Remote, then launched the DJI Go 4 app.  Once they were all communicating, I went into the 3D FPV app and chose the "Cardboard" option and damned if it didn't have it nailed on the first try.  I dropped the iPhone 6Plus into the vr headset and was flying the drone around, sitting in a chair, (recommended) like I was sitting in the pilot's seat on-board the aircraft.  

What a great way to fly this little drone!  The only issue was getting it to lande.  I had to take off the headset and got to the GO 4 app to accomplish that.

what the name of the 3D fpv apps ?

I plan to purchase and try this app. Did you have any video or app freeze ups? The reviews are not overly positive. Worried about spending $20 on a crap app.

Yes, I have video - I will upload some.  No problems, no glitches no freeze-ups.  So far.  8-)
