Grafpad now runs on iPad and other tablets!
Grafpad is now usable on your iPad or Android devices. Instead of right-click, Grafpad supports double-tap on these devices. The touch-based Grafpad is still experimental and will likely cause occasional frustrations. If you experience your browser crashing or giving you errors when loading Grafpad, reloading the page should fix the issue.
