Author here. The goal of Boden is very much that the applications should look and feel as if they were custom-coded for the specific platform. We also think that custom widgets often fall slightly short of the native feel, as other commenters have pointed out. While it is certainly possible to make them 100% consistent with other native apps on the platform, it is a lot of work to get all the details right. And not all frameworks manage to do that.

We wanted to try a different approach. Why not just use what the platform gives you and always get the right look & feel out of the box? That certainly creates its own challenges, like having to provide a good abstraction layer for the core application code. But you do not have to worry about look, feel, drawing performance, interactions with other OS features and the like. And when the OS changes something then the app is automatically up-to-date.
