I used this on “auto” mode where it triggers by itself. Problem was by the time the shutter opened, the big visible lightning bolt had dissipated so all I kept getting was a background glow in the sky.
Also, kind of a funny side effect with this app on iPhone XS (without the home button) is when I’d swipe up to go to home screen, it kept thinking I was changing one of the menus. Was hard to quit out of! Haha.
Anyway as for capturing lightning, I had better results with a long exposure app.
