The iPad-app does everything it should, but shows an inacceptable tendency to crash when no online-connection is available. During offline mode one can swipe only thru the pages, not preview is available as soon as one touches onto the border-area of the page to activate it, the app crashes. It also doesn’t support a regular offline-mode, it always starts with the store page, that would require an online-connection instead of the “on Device” page of My Library, that offers access to all locally stored content. There also seems to be no time-out for trying to establish an online connection to the store, so people waste time and battery-power. The library also shows in offline situations no picture of the cover, only the name of the magazine. So in total, currently just an ‘okay’ rating, with potential to become ‘good’ as soon as these offline-stability issues are fixed.
