Hello
Sorry I was having problems this morning sending the question
I’m looking for which app on my phone to download are used to open videos
that people submit from the form
...

Hello Jennifer,
It will be used the default video app set in the user's device.

EG: if I have set the VLC app as the default video player, then visiting your form, I'll watch your video using VLC.
Hope it makes sense.
