No! If you have a modern device that supports HTML5 and other cutting edge technologies you will see even more features and get to use gestures on our new HTML5 trend chart, but users of older devices still get almost all of Visual KPI's features. Also, if you use Visual KPI on a PC or Mac browser that doesn't support HTML5, we automatically convert our new trend to Flash for you so you get the same great experience without any changes on your part.
Want to see where we use HTML5? Our new trend chart is the best example (video).
