★★★★★Sep 3, 2026
Difficult to use, too many ads

The filing system is difficult to use. An ad pops up too many times. Annoying

★★★★★Aug 22, 2026
Worthless

Bombarded with "offers" and notifications upon opening the app that try all kinds of tricks to get you to click through and sign up. These do not go away after the initial setup. While viewing, there is a hard limit to zoom distance and the image blurs while doing so. This is a simple task and this app is unfit for it.

★★★★★Aug 1, 2026
Horrible

Horrible. All kind of signups just to try it. It’s also rentware so move on to a one time pay one

★★★★★Jul 21, 2026
Can’t select text in pdf

Then what is the point?

★★★★★Jun 7, 2026
Still don’t got what i want

When you open the app there is this blast of “make an account, join premium, do this tutorial, do that tutorial” 😭. What is this warm up mode i keep on seeing oh my god bro just let me open a pdf. I know it’d be a little ironic if I mentioned how unintuitive the features are after bashing the tutorials (is that what those were?) but it is just a pdf editor. It isn’t hard, but it’s weird how obtuse it is. It takes like 5 button clicks to add a bookmark. There are also like 4 toolbars. I’m really only keeping the app because it’s the only one that *allows* bookmarks. Wish they had an option in one of those toolbars to turn off the “Want to practice using a pdf editor before actually using it?”-button 😭😭

★★★★★Jun 1, 2026
Lost 3 hours of work! App on my laptop crashed.

If I could give a -0, I would. Reached out desperately to support for help. I received a generic form email that stated they had an increase volume of support tickets this week. DO NOT purchase this app! Now I am starting my project over from scratch in tears.😢
