I bought this app in December, 2009. Both before and after, I purchased several different camera apps. Its now 16 months later, and this is the only app I use to take photos on my 3G.
The full-screen shutter makes it a lot easier to take pictures without having to contort to hit the little button. The anti-shake feature means I take very few blurry pictures now, and I keep probably 75% of the pictures I take, instead of my previous 25% or so.
Ive only used the flash effect of the app once or twice, and Ive never used the sharing features. But for a quick-launching app that does the trick of keeping my pictures straight, and helping me take them without blurring, I dont see the need for anything else.
I admit Im puzzled by the low reviews this app has received. I use it several times a week and have for a long time. Ive never had any problems with it.
