Currently on Zinio I have 9 subscriptions. I received a free offer for OK Magazine and STAR (they seem to be weekly) and I have yearly subscriptions for: Everyday Food, Macworld, Mother Earth News, dwell, iPhone Life, Handyman-Get Organized and NG Traveler.
On my Kindle app I have subscriptions for Taste of Home & Arts & Crafts Homes.
I also have via its own app: Bon Appetit.
I read all on my iPad 3.
