Thanks to all about the app warnings!
Thanks to you guys, I spent some time searching through various apps, as I'm not so trustworthy. Most looked a bit sketchy or had poor reviews. Most apps, people complained about lots of popups which drove them crazy.
I finally found a good one with:
NO data collected
NO data shared
And so far, NO ads or popups, which is HUGE.
Just a simple utility app. It downloaded in about 2 seconds and is just like using your regular camera. I'm really happy with it!
In the Google play store, it's named, "Color Borescope Endoscope app" by Easy Connect Master Apps
I don't know if they have an IOS version, but it might be worth looking into.
