I built a gutter estimating app for pricing seamless gutter installations. I’m a carpenter, but I spent a few weeks helping a friend with his gutter business years ago. He would spent 45-60 minutes building an estimate for each potential client. The app I wrote allowed him to complete each estimate I’m less than 90 seconds. However he refused to use it because “I’ve always done it this way.” He lost the business and now works at Kroger. Some people just don’t like technology.
