We've been using this app for about a year now and it works flawlessly. It was hard finding the right app that had all the features we were looking for, but luckily we found this one. It works much better than the others I have tried. I love how easy it is to use and how customizable all the options are. Their staff are also very very helpful at making any additional customizations or changes. We've had a great experience with this app.
