I used to carry a pricing sheet on a clipboard and tally up all the individual prices. I thought there has to be a better way. So I taught myself how to code. After hundreds of hours of coding and feedback from users of the first version of window counter, this is how the pro version came to be. It really means a lot to me if you buy my app. User feedback and feature requests are very welcome and important to me. Cheers, Mike Haslam
