Since ProCamera just released the in-app purchase 'LowLight+' I went to the Portland Winter Light Festival to capture some comparisons between different camera apps.
I am the visual comparison type, not the technical type so this comparison is purely visual for you to decide for yourself what image you like better. If you want to find out how the different apps are technically capturing the image I am sure there is plenty of opportunities to find out through a Google search.
The first image in each pair is the original capture focused and exposed with a tap on the center of the flower. The second image was processed in Snapseed with two folder settings: HDR Scape - Nature - 100 and Details - Structure - 100. This processing technique was to show the noise not as a suggestion for the best processing option.
There are obliviously differences in the results. I can see that LowLight+ has much smaller noise particles, with an interesting pattern in this example. However to accomplish this the image is much softer.
I was most surprised by the Native Camera and SlowShutter (by Cogitap) results. Even though without processing they all have very little noise.
