I was phone only, until I learned that Tapas gives the middle finger to creators whose series isn't popular yet, so I started checking out the desktop version in order to help a few creators with a like or two, and a subscription.
Unfortunately, with Tapas 'demanding' that most series must be made with a mobile app in mind, most series are really discomforting to read on a 16:9 monitor which is basically the reverse canvas for what your series is intended for.
So, basically I now subscribe on my desktop version, then check out the comics in my mobile at my leisure.
