Fair enough, It's not an app for everyone I guess.

Yes, I am aware that Photoshop can work with percentages, but unfortunately I don't own Photoshop (I can't be the only person in the world who doesn't have it?)
I use paint.net for most of my 2d stuff, and that doesn't work in percentages, so I felt the need to write this app. It works for me, and has saved me a good deal of time already.
Quote: " think this is the thing to get your head around. You're actually making sprites that will be different sizes on different screen aspect ratios."
Not true, the sprite size varies with the screen resolution, not the aspect. The percentage system uses a user defined aspect ratio (based on the screen size you use to draw your media).
So for example, I draw a sprite in paint.net which is 32 x 64 based on a 320 x 480 screen resolution; and then this app tells me what the percentage value of the screen the sprite size is (in this case 10.0 and 13.3333)
Then regardless of whether it's displayed at 1080 x 1920 or 240 x 320; it will always be 10% of the screen wide, and 13.3333% of the screen high.
This app is simply there to make it a little easier to work out that the image is 10 x 13.333 %
