Cortex Camera ($2.99) is remarkable. You how an iOS picture shot in low light can look terrible, all grainy and speckled? Cortex Camera takes multiple pictures and using some clever algorithms "cleans up" low light images. The higher quality of Cortex Camera photos is obvious on all iOS devices and even on the iPhone 5 with its improved camera the improvement is significant.
