Do you seriously think an app alone can alter your phones camera to see infrared light? You need to mod your camera yourself to do that, its very possible for a low price, look it up ( but I strongly recommend you do this on a less expensive device)
Im not giving this app any less than 2 stars, even though it has false advertising,, because I took a picture of a light room a million times, finally got a good snap, then told my friend that it really works.
I convinced him in some way and he downloaded it, couldnt get it to work, and he beloved that he was doing something wrong with it until I showed him the reviews, LOTS IF FUN IN THAT CASE!!!!!!!!!!!!!!!!!
p.s. I feel bad for anyone who payed for this, or the emoji apps, BECAUSE they ALL come with your
