Snapspeed is an excellent application; however, I consider it overrated. I am using Adobe Lightroom, Adobe Photoshop Express, and Canva. These are probably the best photo editing apps at this moment. There is also VSCO. It is a good app; however, it is not that complex as the others I mentioned. VSCO is excellent if you want to edit a photo quickly and post it onto a social network or something like that. However, mostly when I need such a quick edit, I call for the
best portrait photo retouching services, as those guys know their job very well! And their services are not at all expensive.
