We need an app icon that is simple and looks good. The app design characteristics: simple, minimalist, "Helvetica-ish", "Swiss-y". The colours of the icon can be any of the following: grey, black, red, or white. The background colour of the icon is either red or white.
If it's possible, please don't use a checkmark symbol (it's a bit overused for to-do apps). But, if it's not possible, I'm okay with it.
I like something simple like the TeuxDeux icon: http://teuxdeux.com/
The various dimensions of the file will be this:
57 x 57 pixels
114 x 114 pixels
512 x 512 pixels
29 x 29 pixels
58 x 58 pixels
They all must be squares and in PNG format.
In addition, please also send one vector PDF image file (512 x 512 pixels).
Attached are the screenshot files of the actual app.
