Highlighter Customer Insights

1. Sorry to say that but it was my worse experienceThis is a pile of sh*te...!! It does not open your PDF, just a blank page with a ruler icon at the top and a circle icon to change the with of highlighter... Then it "highlights" in an empty page.. When ticking OK your PDF is replaced by the blank page with your "highlights" ... I tried with different PDF... Same shite.. DO NOT INSTALL!!You can't zoom in on the section you need to highlight.

2. But a bit of features need to be added that is to save the edited pages in files or documents to avoiding it not to miss and another one is to create folder by selecting.The highlighter blurs the text too much that i find it hard to read even though i used light color like yellow.

3. Can you please help with this, am I missing something? Other than this barrier, it gets a 5 star, but not being able to zoom in is pointless.Its very easy, i have to mark in a book but not able to do in more than a page.

4. Is pretty nice.It's not a bad app but there's not a lot of color choices and the words that are highlighted are not as legible so in other words if the text is black, when you highlight the words you lose some of the blackness.

5. But a very good app for highlighting anything.The app itself is ok, but in a document you don't have the option to zoom in while you highlight.

6. But the fact that the highlighter makes straight lines are great and the multiple options you can chose like notes, highlighting ect.

7. It doesn't provide a lot of features, but it asks to go premium and shows full screen ads if you're connected to the internet...it happens every time you open a new pic for editing.Just a wastage of time.

8. This is a very good app to highlight any words or phrases and draw, text in any type of PDF.

9. Started giving me a headache just trying to see what section I was highlighting...and that was with my glasses ON! Make app more accessible for easy highlighting please.

10. Now, i am able mark all the questions and answers which is told in online classes since we didnt get textbooks.

11. You can't save the item to your phone either so I save the item to Google Photos and then in Google Photos I download to my phone.This app is EXACTLY what I need.
