I am a bit puzzled about the negative reviews for this and similar apps as I'm not sure what the reviewers were expecting when they downloaded it. To me this is no different from buying any other digital content like a book or a newspaper. Why would you expect the magazine to be free when you would pay for the paper version? The content is the same whether paper or digital although I would expect to pay a little less for a digital version as a nod to the fact that there are no printing costs associated with it.
This app is free and is a portal to browse and buy either single issues or a subscription to the magazine. I really like that you have the option to buy individual magazines rather than take out a subscription, as I don't buy every month. It was also really handy to have access to so many back issues as they dated back to before I started buying jewellery making magazines. The app itself is easy to navigate, looks good and has lots of live links to take you straight to websites etc. I'm definitely going all digital now as it's so convenient to have everything on my Kindle and not taking up space on the bookshelf or getting tatty with rereading.
If you want really nice digital versions of your favourite magazines instead of buying them in the newsagent, you can't go wrong with this or any similar app.
