I completely understand the desire to access the app from a more affordable device — I really do.
However, I strongly doubt that Shapr3D will support Android anytime soon.
To a regular user, it might seem like just a whim of the company, but that’s not the case. Android is a completely different platform that would require writing an entirely separate codebase.
On top of that, there are so many different Android tablets, with very loose standardization. Even when it comes to something as specific as stylus support, there are already too many variables.
From what I’ve observed, the Shapr3D team prefers to stay focused and not spread themselves too thin, which is why I doubt Android support is coming anytime soon — or ever, for that matter.
