XDV PRO

App works fine. If you actually read the paper instruction booklet, it tells you how to use it. The only thing that's not clear is that you touch "SHOOT" to connect to the phone's WiFi. Then you can download pictures (it's slow), etc. Probably better to use the USB cable, honestly. I will say the App is not very intuitive, but it works.

this is not an intuitive app to connect to your phone. BUT WHEN CONNECTED, this is a straightforward intuitive app to use. THIS IS MY HOW-TO: (1) put your phone in airplane mode to disable wifi & data; (2) on camera, press Menu, Mode, down down, OK; (3) turn on phone wifi & connect to 4K_WIFI; (4) turn on this app & make sure says 4K_WIFI; (5) press SHOOT & you should be in; (6) to turn off cam wifi: shut the cam screen door, then take phone out of airplane mode & go back to regular wifi. ENJOY!

This app *does* work very well. In order to get it to connect to the camera, connect your phone wifi to the camera *before* starting the app. Works perfectly after that. It is a great way to control the camera, giving access to all of the functions that you can get in menus on the camera, but with a better user interface. I'm planning to use the app for recording slow-mo of archery - using the app I discovered how the slow-mo video worked, and you can review the footage immediately after recording without any messing around with buttons on the camera.
