Editors’ Notes

PDF Viewer impressed us right out of the gate with a streamlined interface packed with powerful features. Organizing, editing, and annotating documents is a snap thanks to toolbars that emphasize just the functions we need. Combined with Apple Pencil support, bookmark syncing over iCloud, and other modern capabilities, it’s like having a desktop-quality PDF toolkit wherever we go.

Latest Update Makes It Useless


I’ve used this app for a few months to take notes in school. It’s been beyond amazing. It’s exactly what I’ve been looking for in a PDF notation app. However, lately it’s started deleting my annotations randomly, making it completely unusable. I’ve lost hours of lecture notes at this point. As soon as this issue is fixed I’ll be happy to return to my 5-star rating, but for now, I can’t even use the app and am forced to purchase another option.
Update: Spoke to support and essentially every answer was “Well, that’s not our fault. That’s also not our fault. That’s an issue with a third party, and not our fault.” I understand having issues with third parties, but if the issues are so severe, stop advertising these features until the issues are worked out! Since then, the app has started freezing and crashing every single time I try to use it for more than 30 seconds, losing all my changes. But hey, that’s probably not their fault. This app would be absolutely perfect if it actually worked like it’s supposed to.

One positive note: their support is very responsive and gets back to me quickly every time.

I'm very sorry that this is happening for you! I fully understand how annoying it must be to lose hours of work. We want to prevent that from happening, so could you write us via the in-app feedback chat so we can take a closer look at this as soon as possible? Thanks!

Wow! First your response time to any issue is reliable and fast. I had some questions on an older version and you helped resolve them. BTW— the problem was me. Sincere thanks for not making me feel “non-savvy.” I am totally impressed with your product and every update make a useful product better! My husband watches me use it and now he wants to use it for his work as a physicist. It is convenient for research documents as well as I gotta run and don’t have time to read this article. There a tons of reasons to use this app that maybe I wouldn’t use, but could. Totally happy and impressed.

Thank you so much for this amazing review! PDF Viewer is an app for everyone, from teachers, to students, to construction workers etc. We are very glad that your experience with our support team was pleasant and it's also really great to hear that your husband is thinking about using it for his work. I hope we can keep you satisfied with our future updates!
