Its OK but...

Im no fan of Adobe, so I tried this alternative but its lacking in some basic features.
This does do basic virewing and printing of complete files acceptabley, But…
It wont let me print a custom list of pages like Adobe does, Like Print Pages 1,4,7, 12-20, 72. Instead I would have to print each of those pages or ranges, one at a time.
First, it starts off im Thumbnail mode all the time, cant seem to turn that off as a startup feature. Only developers need theumbnail mode, the rest of us just want to view pages in as full a screen real estate as possible. Also, the search feature is weird - it presents the hourglass for several seconds as you beging to type the first letter or letters of the search word, and it crashes ofetn after one or more searches. It doesnt highlight the search results on the viewable page, instead it opens a search results thumbnail list on the left of the scren even though search box is on the right and displayed page is in the middle.
Also, there should be a navigation pane that displays current page number and first and last page number that lets you quickly navigate to top, bottom or a specific page number.

Hi HomeDocNY, Thanks for your review. You can export select pages as a new PDF and print as one. Here is a tutorial https://support.kdanmobile.com/hc/en-us/articles/360000608514-How-to-Export-Selected-Pages-as-a-New-Separate-PDF.
Also, for the thumbnail mode as you referring to when it displays the list of files? If so there is a thumbnail and list icon in the bottom right-hand corner, just click the list icon to switch the viewing mode, if you are referring to something else, please kindly email us at appservice@kdanmobile.com with more details and we'd be happy to assist you.

great but would be even better w some improvements

i switched from adobe to this app because of how slow adobe became on my mac even tho it's updated to the latest version. I solely used it to view my textbooks and do some little highlighting here and there, sometimes printing but not musch really. AND, let me tell you, the moment i launched this app, it felt so fast compared to adobe. also, it felt so intuitive and way easier to use for someone who doesn't know much about how pdf readers work. What i love about it is the different colors of highlight i can pin on the toolbar and switch from and how it doesn't crash or lag obvs. tho, some improvements for features could go a long way such as improving the pen tool and the drawing tools in general because when i freely draw a line or insert a shape it takes a while to appear on the screen and sometimes i have to close and reopen the app to see it after saving it. also, more printing options could be better as well because the printing box has fewer options than adobe's to be used for printing.

Hello Hébâ, thank you so much for rooting for us! We will definitely continue optimizing our app to provide a better service for you. :) For the save issue, you could use "⌘command + S" to easily save the edited file. If you choose to "Automatically save the change when closing a document" in PDF Reader > Preference for setting, any change will be auto-saved! Please feel free to give it a try. For more tutorial article, please visit our Knowledge Base, https://support.kdanmobile.com/hc/en-us/categories/204531528-. Moreover, could you please let us know more detail regarding the pen tool and drawing tool? Please contact us at helpdesk@kdanmobile.com with your device information, OS system, does this issue happen to all files and will it also happen in built-in "Preview"on Mac, thank you!

Squirrely, but manageable

This program mostly does what I need it to do for free. I just needed to annotate my PDF calendar that I distribute. It does basic functions, but when it comes to editing, it's SUPER SQUIRRELY!! Trying to edit annotations that previously been added to the calendar is SOOOOOOO ANNOYING!!! As soon as you click on text items, even to move it, it automatically changes the text font and size, which then requires me to reset the font and size for every item I have to move. For lines and shapes, if I modify them, they automatically move to another location on the document (the same location every time) and I have to move them back. Thats rediculous. I would pay money to unlock additional features, but not for an application that's so unrefined.
