I assume you already tested the Pro Mode of the installed App where you can set ISO, White Balance, AF etc manually? There is no other way then testing a bit what suits you best, one likes an app for some reason, another one another app for another reason. Apologies, without a bit of reading and testing it will be difficult to find what you are searching for.
In my eyes the quality is good enough in good lightning conditions and I think what one finds good enough is quite subjective…
