This is, basically, Total Guitar magazine on the iPad. Now I know that sounds obvious but given all the 1 star, 'it's not free' comments you'd think people would realize this. It's a high quality magazine which reviews guitars, guitar gear, song notation for guitar, guitar players ... I think you get the picture. It looks exactly like the magazine, the picture quality excellent as are the reviews.
Since they (the company produces a lot of magazines) are produced in the UK the cost in the US was high, I always preferred this (and Guitarist) to their US equivalents so it's great to be able to get these at a reasonable cost. Of course all the (minimal) gear ads are for the UK, but that never bothered me even when I purchased the original mag!
I much prefer having these on the iPad rather than the paper, now I don't have to throw away my old mags anymore.
4 stars since you can't jump to pages from the table of contents
