I am (was) a casual Photoshop user. Now and then, I need a tool like this to take a background out of an image, or project een image on a 3D object such as a well.
For more than a decade, I have been pulling my hairs out every time I tried to use the program. I am a pretty skilled computer / software user, but I never managed to get over the dip of becoming an efficient user. In addition, the hefty subscription charge that was introduced does not really make sense for light users such as me.
Now, in my role as coder of my own presentation design app, I actually need a PS-like tool again to manage images that need very precise dimensions and DPIs (something irrelevant in PowerPoint). An inability to create a simple background image that scales on retina displays @2X in less than half hour with the final blow.
So I tried Sketch and everything was done within 5 minutes without the need for any tutorial. Creating the background, adding text, adding shapes, scaling, exporting. Highly recommended!
Sketch is a role model for SlideMagic. The software was started as a graduation project (actually by a student of the same university I got my Computer Science degree), and then moved slowly but surely over the course of a decade to become a market leader.
