As for the robot, I was going for something cute, like MailChimp. It was picture I took of a friend's painting. Awesome painting, but didn't translate well to a pro icon. Do you think a robot could work if I got a pro version done at Logo Tournament?
I do plan to make it easy to try it for free. Also make it much cheaper... say a flat $5/mnth or something.
I actually abandoned it over a year ago once I launched and realized there are 41394 invoicing apps and I don't know how to market.
Specify a target width & height, and users will have a frame that size in which they drag/zoom their image to make it fit. Very much like how Facebook's profile image cropper used to work.
