Best epub reader: why not update it? – Marvin 3 Review

A couple of years ago, I tried multiple epub reading apps, and found that this was by far the best. I was about to pay for it when I noticed it hadn’t been updated recently. Neither had the developer’s other epub apps. If and when this app shows signs of being maintained, I’ll buy it, but I don’t want to pay for something that might stop working with the next version of iOS.
