What is the best iPhone app that shoots in high quality TIFF/RAW format?

I'm looking for an app that shoots higher quality images than the default iPhone camera takes. I have an iPhone 5s if that matters at all.

Don't see how an app would be better able to use the camera sensors in the phone than the phone itself.

The default camera compresses the images into low quality jpegs where as these apps I have been looking into save them as high res tiff with more information and therefore better quality. Was just asking to see what is the best one.

Default Camera would be the best and If you are looking for some good security app you can try Leo Privacy Guard and secure your device completely.
