Some think that the red and green produce an eye-sore, but in preferences you can change the colors. The reason is that the red and green font and the icons they provide are light-hearted and I think meant to be fun. There is no question that in its register searches and summary reports it is damned powerful! I have always called Checkbook Pro by my nickname for it. But Splasm is a conservative company and the long patient wait has allowed them to refine the app. I just finished writing Splasm with an exhaustive email where I recounted the problems and fixes that have made Checkbook Pro an inexpensive alternative to the likes of Banktivity 6 and Quicken 2017 for Mac! Splasm has always moved almost frustratingly slowly in implementing changes to the software even when users ranted that the company was doing just that on their forum. I am intimately acquainted with Checkbook Pro for as long as it has been out.
