Awesome tool. Does what it's supposed to, very easy to use. Highlighting actually works. Hold your finger over the text you'd like to highlight and you can do so. The option to Save As... is available so no more "Read Only" flag issues. It just works!

It's a good app... There should be an option to save in the file itself. If you write something with pencil and click on the tick mark, it's temporary. So need to save again. And even then it's not rewritten. Need to save time and again in a different file. I think along with save as there should be another option to save.

Cannot open the file sfter editing. Before I discovered this: Functionally simple and clear. Allows you to write on PDFs and add note bubbles. Save when you are done, with the option of save as. A highlighter would be be a nice addition but is not needed. The pen line thickness is fine for underlining.

I don't want to waste space in my device with the bulky, buggy Adobe applications. I do light reading on my mobile and sometimes it really pains not able to highlight the very beautiful lines I come across. Either I have to jot it down somewhere only to misplace it or write in a Google note and mix it up with other notes. This app just gets the job done , HIGHLIGHT. And there are some more decent features too but anyways 2mb only and get the most important task done for me. ๐ŸŽ‰

The app is good, but selecting text is a nightmare; the page moves all direction when trying to select text. I think you should stop the vertical page movement gesture since vertical page scrolling isn't allowed. Thats the only major problem i faced. i will give 5 star when that is fixed.

So time sharing to work on this apps as it slide where and there from the work space and no undo option. Undo can done if you close the apps. No guideline provided for working a new one. It would be the good apps if this features of guide or help include in the apps. Tis is my suggestion.

At first the app was too helpful for checking the online papers of students but from past few days non of my file is saved and if in case it is saved the pdf doesn't opens and it closes automatically by popping pen&pdf has stopped working. I tried installing the app on my other device but same problem has arise.. would really appreciate if you fix the bugs if there are any..

Great app... Reading PDF in this app as if you are reading a physical book because you can underline, highlights, make small notes. Some time I get difficulty in selecting the lines please fix it so that making every underline don't take that much time.

I spent two hours taking notes on a neurology course i had on my note 9, then i saved it. Problem is the file is corrupted and wont open with any pdf reader and indicates 0 bytes of storage. thanks for wasting my time taking notes that i dont have access to... Btw, never had any problem with other aps such as this one like write on pdf..

Not useful : - 1. App showing Add page but there no option delete page. 2. There No white color ink option. 3. before menimize and after maximize App save command not working and all annotations wash out in midway. 4. (no page swapping top to bottom) If the page is left to the right then only the next page comes.

Actually everything is is nice in it but the fact that only once my files saved with all the markings it's upsetting I tried saving many files with marking but it always shows that this app stopped working!!! It's just useless marking !!!! Cause after it I am unable to save my files

Sha. S. Jan 5, 2021     

Very good app. The reason I have given it less stars is that highlighter does not work on some pdfs. Don't know why. Otherwise its perfect and easy turn use. Good job

this app is very simole and organized , te quality of the pdf being trasfered is very good! i love the note taking function to make comments within the pdf .i took away a star because i cant figure out how to use the highlighting function. it is clear there is one and i can costomize it in settings but i dont know how to actuall highkight the pdf.the underline/draw is clear and the eraser but i wish there was a littleQ&A, or. short tutorial. if someone could get back to me i would appeciate it!

Practicar Joker...but not funny. It lets you annotate PDF files, however it doesn't save them in a format that can be read. I marked up several different PDF documents and try to save them and no standard PDF readers could open it. Such a disappointment

- make changing highlighter colour more streamlined. Have to go to settings every single time. -can't open pdfs larger than 150mb and above (java lang exception ran put of memory) Love that there's no disruptive ads while i read my textbooks. Good work. I'll

Pen&pdf is the best app I ever usedfor editing pdf pages. I really like this app so much, it has pen so you can draw or write on pdf with your magic finger๐Ÿ‘†......... uhh just kidding. But this app is really a good for any pdf. So I suggest you to install this cause it's the option you to write on pdf with your figer. I hope this this is helpful for you!๐Ÿ˜Š

The app is excellent but the app would be perfect if some updates are done to it such as having the options to change the colour of the pen in the head bar itself .

Hen. R. Oct 22, 2018     

I will give this app 5 stars if they can add floating icons to change pen and high lighter colours and add a periodic auto save. Besides that its the best pdf whiteboard I could find.

Xer. Mar 24, 2020     

Cannot exit full screen, cannot change color without going to settings, with my spend I still have to use two fingers to move the PDF, unreadable by other apps when saved

Dan. H. Oct 19, 2020     

Zoom is too sensitive and constantly moves around when trying to write with one finger. Save as crashes every time.

Mee. S. Feb 6, 2020     

I have marked the PDF and saved it too. But when I opened it, the PDF was not marked. What is the issue ? Please see to it. Inconvenience in using this app.

The side scrolling is horrendous and there is no option to change the page display, for example to vertical continuous scrolling.

Bim. V. Apr 28, 2020     

Would like the app developers to give more efficient programming function. Nice and simple app for students to study in PDF. The best thing is annotation.

Tar. S. Mar 5, 2019     

This app would benefit from a toolbar with an option to quickly switch between pen, highlighter, eraser - and to change color and thickness.

Atu. P. Nov 6, 2019     

Though in setting shows all features like Highlighter, striking etc but there is no option at all in anywhere to select from Pen to Highlighter etc....

MAN. P. Jun 7, 2020     

Useless app.. i spent 2 hour to make a change on pgf file and choose save as option.. but file is not saved.. total waste of time and mind irritated... DON'T USE IT...

Akh. Nov 4, 2019     

5star Best app Go for it. Please add few features 1. Scrolling pages down instead of sliding it left 2. Total pages and the current page no. Should be visible at bottom of the the app. Please make these two improvements

Simple and effective! Extremely handy to makes notes on PDF documents (instead of printing everyting :)) ! Really thanks!

Jai. O. Jul 2, 2020     

When I highlighted everything and then I went back .. i did not see the PDF while opening the file .. it's very disappointing..

Pro. May 18, 2019     

Would appreciate if the option to change pen and eraser size is made available on top of the canvas instead of the settings page.
