This is a great app but the update…

The update looks cool but I miss being able to see all the pages from a distance so I can quickly find a specific page in like a textbook with hundreds of pages. Now I have to scroll instead of selecting a page. Any kind of quick navigation feature would be very welcome. The mark up feature needs work as well, the way I usually annotate my pdfs is with the apple pencil but the new markup pen feature doesn’t register brush strokes half the time, I had to start writing in cursive to keep the momentum for when the pen actually works lol, and it’s kind of illegible. I would like it if we could write/draw on the notepad stickers instead of having to type too if possible.

Great mobile pdf app.

I use a lot of PDF software to annotate site plan maps and UPDF allows me to use my iPad and make edits on the go. Compared to Adobe annotations UPDF handles large amounts of annotations surprisingly well on the iPad. I have an iPad 6th gen and it’s been abused a lot so it runs slow and lags out on occasions but I am very interested to try UPDF on desktop and if I can get my job to agree to it maybe buying a license for my work PC. Highly recommend and I love the feature on the free version but I will definitely be getting The paid version so then I can use cloud space to be able to transition between devices easily as well. Only issue I have encountered is when editing a PDF of my tablet crashes no info was saved unless you manually save it periodically. Maybe this is different with cloud storage space. If so then great but if not I would definitely like the ability for the pdf software to make saves as edits are made just to not lose any data.

Ridiculous cash-grab

The app is basically a disappointing preview that may trick you into accomplishing something— just for you to realize none of your progress mattered unless you pay for it. You can’t save, download, or export your progress; many of the features will be missing; any amount of work you’ve done will be automatically erased if you minimize the app for long enough (maybe 20 minutes… think, a phone call came in and you had to take it).

This app is worthless until you get through their paywall… and even then, I can’t vouch for how much better it may be— as my experience, being consistently disappointed, hasn’t justified paying them a single cent. A lot of incredibly basic features, such as changing the font size after typing into a document, weren’t even options; it’s not promising.
