Our app has been temporary taken down by Apple due to the "contain inappropriate content" issue.
So if you lose the app, you won't be able to re-install it directly from the App Store. Until we have cleared this issue with Apple, please transfer your purchases to iTunes just in case anything happen.
Please also note that, some titles containing violence/pornographic will be removed from the next version as well.
Sorry for your inconvenience,
Manga Storm Dev Team
