Most of my filming is done on the move in or out of a vehicle or with my drone. I'm one not to just turn it on and let it go. I'm constantly changing my shots utilizing different POV. I agree with it having it's place and it does for me. I find the apps quite useful.Got it but didn't find it useful for snaps, if I'm switching the phone on, I'll just use the phone camera in 99% of cases. My phone wifi also goes to sleep when the screen is off so have to wait for it to wake up. Was very useful in the car for making sure the placement was ok but not for the snap scenario.
Also of limited value with selfies but got some great pics of me and my wife using the 30 shots over 30 secs mode.
The app certainly has it's place but not for the use cases I was checking out. I also had the camera setup for the wifi remote so a bit of messing about to be done.
