I purchased the WatchTime all access bundle for $49 .95. It directed me to this app for reading the magazines and newsletters on my iPad.
I had some difficulty getting started with the app but the current version has fixed the problems. Its a good app for viewing the magazines and newsletters.
The one point of inconsistency is that the ad for the All Access bundle says that you get access to all their archives. That is not true. I tried to access the 2012 Buyers Guide and one other magazine that was apparently considered "special" and those publications had additional charges ($15 or so).
If you do not buy their all access bundle, and only wanted to purchase one or two of their publications through the in app process, I suspect it would work fine and you would be happy.
