I have it too on my Android phone, but the screen is rather small for my fingers, so I'd like it for my iPad as well, but I can't find it.
In fact I can find nothing that has cubes with numbers for iPad. Maybe iPad users are not supposed to be smart enough for that - maybe iPad is for dumb people? Should I get an Android tablet next time?
Which one will be the best for Windows 10 device. I have asked hp customer service about they can't help me. So if anybody can then please help me in that issue. Because I can't use this software for a long time.
