I'm really sorry. I know some of you are waiting for CalcPad, and it just doesn't seem to manifest itself.
There's a reason for this, and it is, that I learned some lessons from the launch of ND1, and don't want to repeat the same mistakes.
ND1 launched quite capable. It was the only programmable calculator app on iOS, the only one with an HTML5 display, user-extensibility, cloud storage, downloadable folders, data-exchange with a desktop machine. But very few cared about these specific features (which, as far as I know, are still not implemented elsewhere). Instead, people cared about features that weren't implemented well: easy graphing, an algebraic mode, CAS functionality, documentation, good looks. Some of these are still outstanding and/or lacking.
I've been working on an internal engine and framework that is good. Additional significant development has been done on a major new feature that has the potential to make the app much more relevant than it is today. All this will come to fruition, but it takes either time or more manpower to accomplish the ambitious goals with this project.
Now. The iPad product is even more ambitious. And for a successful launch, it needs to do all the things right, that I know how to do right. That includes polish that ND1 never got (not because I'm mean or inept, but because I've been focusing on functionality first).
It also includes having an option for a CAS. I just announced it for ND1, and it (internally) became available for CalcPad at the same time. This is an important milestone.
I know a few of you would be happy with just ND1 for a bigger screen. But I know (or fear) it to be not enough for the average new user.
So. I apologize for the long delays to those who are waiting! I'm looking into ways to speed up implementing the road-map (which, in actuality, extends quite a bit beyond what's said in the road-map post.)
