For those wanting to know, I used a screen from my own phone/tablet for Anais's phone. I inverted the image for color/transparency but yeah. ((First is the actual "screen" and the second is inverted.))
The Camera program I use is called "A Better Camera" and it comes with the Spiral in the "Grid" section of the I use "A better Camera" App. It's in the "Grids" section. APP
this is probably violating the AUP but hey, they deserve the ad.
