The APP is a necessary evil to use the F7N/F7NP. Since the Camera Wifi will not remember its setting of ON across a power off, you must go through enabling the Wifi on the camera and synching with the phone, each power cycle. It does not provide function by function setting instructions for the camera, so it is a lot of trial and error. Once linked to the app on the phone, the camera will not respond to many of the manual selection functions. It can also get out of step with the APP. Many other issues with F7N/F7NP user interface but not with APP.
