This App was designed primarily for my artist girlfriend and her artist friends to help them calculate costs for their works. If somebody else finds it useful/helpful then that's great, but please note it is currently designed to calculate 2 things only - more options to come.
1. calculate total selling price to gallery based on amount retained by artist.
2. calculate artists component of sale price once commission is taken by gallery.
3. shows some basic sheet, canvas and photo paper sizes.
can also be used for calculating discounted costs for sales items when shopping.
