Used to be 5 stars.
This WAS the perfect sales tax app to use with my cash paying customers. That is, until the latest update. The two screen format is more awkward to use and the new colors are difficult to see. I also overcharged a customer because the update changed the tax rate and with the two screen format I didn't see it until later. Yes, I got the app for free and I shouldn't complain but, I want the old version back.
