This app really does address the void of useful softeware in this industry. Built off of Filemaker does ensure a level of stability and cross platform user experience. If you are familiar with Filemaker then learning this app is a snap. And if not, just a little extra time and you will have things falling into place nicely. The developer does seem very interested in users feedback and takes suggestions seriously. Which is rare these days. It IS worth checking out, despite some people's obvious misinformation.
