A Camera App for the GT-i9500 ( recommendations )

We all know that most our photos get blury because of the shutter speed which is 1-2 seconds. Nobody found a way to reduce this speed to zero, but this phone's camera is still not very bad. So I would like to question all the i9500 users, what is the best camera app for this phone on KitKat? Or are there any mods or any other things that increase photo quality? I know how to play with the settings, so don't recommend me to do this. Stock settings are medium.
I am also using A Better Camera from the playsotre. But anyway, I am wondering if there are ways to increase our camera.
Thanks in advance!
