Recommend a 3rd party camera app?

Hi,

I was wondering what people's opinions were in reference to using a 3rd party app from the app store for the camera (both photos and vid)...where the app will let you lower the resolution for taking pics and shooting video so you are not forced to use the native setting in iPhone? Not sure why Apple refuses to add this feature and forces everyone to shoot in the highest setting which eats up storage space.

Anyways wanted to see what others used before I decided on which app to go with.

Thanks!
