4 stars: An absolutely great app. Amazing for reading SJ manga! I just wish you could take screenshots while reading. It has a great variety of manga to read though. And I desperately wish for a subscription service that lets you read everything you have on this app! With that being said, it's an amazing app by far, but it has some issues here and there that if they were fixed, this app would be nearly perfect!
3 stars: I love this app. But people seem too critical and put bad reviews just because this app only serve them 3+3 chapters (beginning+latest). Off course that happened when you don't pay! So, serve us better, Shueisha! I don't mind to pay extra to read the lost chapters, and get rid of those ads. And also, there're a lot of bugs! You need to update this app ASAP! I'll give you 5 stars after that.
3 stars: Great content, you can't go wrong with Jump. The reader on the other hand it terrible. It used to be quirky but usable until a month ago, and now it's almost impossible to read with any kind of zoom, for the pages will turn for no reason, it won't let you see the whole page before turning, needs precise finger movent to just turn move around.
4 stars: Nice app for reading the latest manga chapters. But sadly not possible to read all chapters. If you want to read all chapters get the Viz Shonen Jump app with subscription. Kinda confusing that there are two apps. I wish this app had a subscription option to read all chapters, as this app looks a bit bette...
