Allows more close-up shooting of focused subjects than default iPhone camera.
Pro Manual controls

Pro Balanced features to user experience and ease of use
Pro Apple watch compatible
The apple watch provides a preview, remote trigger, change mode (picture to hdr, record video, low light+) possibly more.
Cons
Con Does not detect faces or zones
Con No video recording mode
Con No panorama mode
There is no panorama mode offered in the app, meaning if that is a needed feature a different app will need to be used making this not an all in one solution.
Con No HDR
There is no way to do HDR in this app asides from manually doing it yourself and processing it in a 3rd party app, which can cause alignment and ghosting as problems.
Con Features presented as exclusive modes cannot be used together
For example burst is a mode, and so is the timer, but you can't do burst photos with a timer, or burst mode with a stabilizer. None of the following may work with each other in tandem: Normal, Stabilizer, Timer or Burst. This limits the functionality of the app, which may not be understood before purchase.
Con Not free
Con No panorama mode
Con No face detection or zones
Con Exif data faulty or non-compliant
A better file renamer was unable to read Exif data from files produced from procamera.
Con In-app-purchases (IAPs) make this app mildly expensive
