Only for Tablets?
Yes, after thorough consideration and evaluation, we believe that reading this comic on a mobile phone would be a limited experience. Much of the charm of these comics resides in the large vignettes, the detailed backgrounds, etc. We believe that tablets are the nearest thing to reading a traditional comic on paper, and that this format provides the most enjoyable experience for the reader.

Just iPads?
At the moment, yes. But an Android version is planned for a later date.
