We support Chrome, Firefox, Safari, and Edge internet browsers on desktops, notebooks (aka laptops), cellular equipment that support full html, netbooks, and tablets that are running Windows, OSX+, IOS, or Android.
Note: When using a tablet or other other touch screen devices, the drawing tools work best if you have a thin Stylus, since the tip of a person's finger may not allow for accuracy for the borders.
Otherwise, if you do not need accuracy for the borders then you will be fine.
Note: We do not support Linux.
