I was planning to do an Ubuntu Touch port first actually. I will consider Sailfish (Qt-based, I presume). I can't make any promises as I have a lot of other stuff to do.

In fact that's a big part of the reason Habit Jewel came about - I tend to focus with laser-like intensity on my current project to the detriment of all the other things I want to do on a regular basis (besides washing and eating though, well for the most part... )
