HCSS Plans  is a web and mobile application; there are no network and server requirements for your IT department to host the software. All of your data is stored in the  HCSS Cloud  for access anywhere you have an internet connection. You can also access uploaded documents in disconnected mode. HCSS Plans  is supported by Internet Explorer 11 or better, Firefox, and Chrome web browsers. (We currently do not test on Microsoft Edge.) The  HCSS Plans  mobile app is available for Apple iOS devices, including the iPad and iPhone. HCSS recommends the latest generation iPad or iPad pro (10.5 inch) for best usability. At a minimum, the app will run on the iPad Air or iPad Mini 2, with iOS 9.3 or higher.
