Good try, but pass on this one – ManCam - Super Manual Camera Review

First problem is that the app doesn't even function correctly. I tried different combinations of ISO and shutter speed and they had no affect on the resulting photo. The combinations I chose should have resulted in over and under exposed pictures, but in camera roll they were all identical. The second problem is that the person who wrote this app has no experience with photography. Anyone who uses a camera regularly knows that all settings should be adjustable from shooting position. The failure with this app is that you have to first tap on what you want to change, then adjust the slider. By the time you've done that the moment is lost. The two most common settings (shutter and ISO) should be adjustable from the same screen. Lastly, the app doesn't remember your settings. Why does an app from 2017 work worse than a manual film camera from 1950? Every time you open the app, you have to set everything over again, even flash. All the manual film and digital cameras I have from 1950 to today stay exactly the way I set them, even if I don't use them for 10 years. My advice to the developer: grab a DSLR, learn to shoot it manually (and respond quickly to changing subjects), then fix your app. Best of luck.
