Firstly, the True NightVision app from interealtime.com does not allow you to see in total darkness like real night vision would. It basically amplifies the light by around 15 times which increases what the camera can see.

This means that you need some light to use this app. Another thing that I didn't particularly like about this app was that it could only save images at the highest resolution of 1280x720. The app also over compensates the light quite a bit which means photos become quite grainy.

What I did like about the app however was the rather cool filters that you can employ into the program such as monochrome and even a goggle like night vision green filter. The zoom feature was also rather cool.

Final Thoughts?

As opposed to the more serious NightCap app by interealtime.com which is far superior, True Night Vision seems more suited to the younger market and I'm sure kids will enjoy this app on their iPod Touches and iPhones.

Just don't expect "true" night vision which is impossible on the iPhone.
