5 stars: Have been using it for a while and I have to say it is a lot more reliable and user friendly than the alternative *cough* Lightroom *cough*. Handles the RAW files from my Fuji X100F with ease, rock solid to use and plenty of features. Makes my photos look great and easy to export them. The only caveat really is you do need a fairly decent processor and memory- I have a Samsung A7 (2017) and it can just keep up if I shut down other apps first. Processing 24MB RAW files will take its toll on any device though.
3 stars: Crashed during browsing and tapping to toolbar pen button. Sorting by date for Home folder is not functioning. Browsing UI is too raw.
4 stars: I have a big of problem while editing RAW photos. The same raw file is showing different colors in Lightroom-Snapseed and Photo mate. Photomate sure does give some extra options but colors is something it is messing with. Changing color space doesn't change a thing. It'd be a great help if I'm told why such differences and how to get around it.
5 stars: useful RAW editor and lightroom fascimile, better than Polarr for actually processing raw files, especially sony .arw files which is what I shoot in. I use it on my android app-enabled chromebook, as lightroom mobile and polarr didn't cut it. Not the fastest editor, but you have to realize the limitations of the hardware you're working with (android device vs full fledged mac/PC), can't fault it too much for that. Main gripe is that noise reductio...
