FAIL. Cortex images fuzzy compared to Apples Camera app

UPDATE: After two weeks of shooting with various iPhone photography apps, I cannot find the merit of Cortex Camera. Cortex Camera images continue to be the shots I delete. If Im doing it wrong, it sure would be helpful if the developer would provide an FAQ or tutorial.

I keep taking the same photos on an iPhone 5 with both the native Apple Camera app and the Cortex Camera app. I keep hoping that the Cortex Camera photos will be clear and lucid. The Cortex Camera photos are fuzzy when compared to the same photos taken with the built-in Camera app. Neither the Cortex Camera website nor the app provide a tutorial or a FAQ to explain to the user how to correctly use the app. Cortex Camera needs to provide more explanation on how to take superior photos using their seemingly lackluster app. Until then, dont waste your money. Overpriced disappointment.
