Adobe Digital Editions 4+

Despite its presence on the App Store this is a non-functional app in every meaningful way. Yes the software does run on iOS and does respond to user inputs but that is all that can be said. Page numbers in contents pages do not function correctly. You can’t jump to a page by pressing the page numbers which is fine if it’s a 10 year old pdf but unacceptable for content specifically made for the platform. The jump to page feature does not work at all, it’s purely decoration. Content will randomly not display at all depending on the zoom level. Each page seems to require a different degree of zoom to actually display content. This all complements the horrific DRM implementation: if you don’t sign in before downloading something you will permanently lock yourself out of opening that file!

All this app is is a glorified pdf reader with DRM and it fails to do either. A legitimately unusable piece of software. It may be free but you pay with your sanity.

I only downloaded this because I had to for a uni book, and I still can’t even access it. Is this really an adobe product? I have the creative cloud since I’m a design student and use a multitude of adobe apps with ease. Nothing has caused me more frustration than this app. If you have an iPad don’t bother with this.
I am now having to view my book chapter by chapter while studying for an exam because at least this way I can view it on pdf viewer.
The introduction book on this app doesn’t load properly, half the pages are faded, pixilated and hard to read. I have deleted and downloaded this app multiple times and the issues stayed the same.
Don’t bother with this app, save yourself the headache and look for alternative solutions.

Unfortunately, the book I bought was restricted to Adobe Digital Editions (which was not disclosed). As the other one-star reviews indicate, this is barely a reading app and worse, it is extremely buggy. I opened the iPad version and there were blank pages and pages with very faint writing throughout - it turns out that this can be fixed by switching to dark or sepia mode, but this bug has been reported since 2021 and nothing has been done to fix it (or indeed even just to default to sepia mode so you don’t think your file is broken). In future, will always purchase paper rather than anything that is limited to ADE.
