I was very glad to find this app as I can now buy and read that wonderful magazine abroad. But the app itself is really not very good.
1. sometimes magazines which I downloaded already disappear and I have to download them again (just imagine, you wanna read it in a train and find out that it is gone)
2. that is just like a PDF version, not a comfortable way of reading (just comparing with National Geographic), no additional grapics or videos
3. the app does not remember where I was reading last time, everytime I have to search for the right page. Every PDF reader is better
4. and also the price of the magazines! Normal paper issue costs 5,95 euro, that uncomfortable PDF-like-issue is only 50 cents cheaper!
Well, as I dont live in France and really love that magazine, I will certainly use that app also in the future as I have no other choice, but Im really disappointed!
