Night Vision (Photo & Video‪)‬ 4+

The theory about how it works makes some sense. Use the camera lens at its widest aperture to gather as much light as possible and "see" an enhanced view of the surroundings, as compared to naked eyes.
The problem is that your device certainly is not equipped with the hardware to do this job effectively. Consumer cameras (and phones/tablets) are generally not equipped with the type of monster lens that would be required to squeeze some light out of what your eyes would perceive as darkness. That's why they come with flashes. Don't think for a minute that some obscure app will turn your tablet into a military-grade set of night vision goggles. Two things will happen: (1) you'll find yourself staring at a dark screen and (2) you'll close the app and turn the iPad around and use the display as a lighting device.

Those who are just seeing a black screen aren't taking the time to learn how to use it. The idea that all of the positive reviewers were paid is just absurd - this is a $2 app, people.

Of course it's not IR, and it's not claiming to be. The picture is enhanced digitally, so you do need at least a little bit of light - enough for your eyes to see with, and maybe a smidgen more.

Yes, it's grainy - but it's a *cool* kind of grainy, because it really is actual, functional low-light vision, giving you a dramatic amount of detail where the regular camera would only yield a blank screen. It's bloody well amazing, and I couldn't recommend it more highly.

If your truly looking to see in the pitch black, DONT BUY THIS APP. It's only made for soft lighting. It's like a camera with little extra enhancement. And whoever said that you have to mess with the "settings" so your capable of seeing in the dark, yea well your wrong. I messed with all the settings and what do you know, just another garbage app and complete total waste of money. I can't believe you even charge $3 for this app. What a rip off, I feel robbed. Not even 5 minutes later and I deleted it even after paying $3. Bunch of hustlers, that's all they are...
