IPHONE: Now you can use iAnnotate on your phone, with all of the great features you’ve come to expect on your iPad.

IPAD PRO: iAnnotate works great with the iPad Pro. Automatically annotate when you use the Apple Pencil and easily pan, zoom, scroll with your fingers — no tool switching required. Get more work done with iOS multitasking and smart keyboard shortcuts.

ANNOTATE: Choose from the pen, highlighter, typewriter, stamp, straight-line, note, underline, strikeout, photo, voice recording, arrow, rectangle, circle, and date stamp tools.

CUSTOMIZE: Drag and drop tools to your custom toolbars. Swipe between toolbars, or open the Toolbox to access all your tools.

ACCESS: Connect with Box, Dropbox, Google Drive, OneDrive (including OneDrive for Business) or open PDFs directly from email and other apps.

SEARCH: Search documents in your local library and throughout your cloud storage.

SHARE: iAnnotate saves your markups directly to the PDF, so they can be viewed and edited in external PDF readers.

FLATTEN: Compress your annotations onto the document to prevent modification. This is useful for preserving signatures or for preventing recipients from deleting or changing your annotations.

WEB MARKUP: Open a web capture tab and find the site you want to mark up. iAnnotate will convert it to a PDF for annotation.

NAVIGATE: Explore your documents by thumbnails, bookmarks, annotations, or search results.

UNLIMITED TABS: Open multiple documents in tabs, and easily navigate between them, on both tablet and phone.

TWO DOCUMENTS: Work on two documents side-by-side, for even greater productivity.

MANAGE: Arrange documents by folders and sort contents by date added, date last opened, or alphabetical order.

CREATE: Create brand new PDFs with blank, lined, or graph-paper pages.

MODIFY: Add, delete, rotate, and rearrange pages in your documents.

SUMMARIZE: Forward a summary of your annotations as an email or a new PDF.

SECURE: Full support for the iOS Data Protection and Keychain functions.

Best iPad app for academics

I use this to review journal articles, papers, student assignments and other University documents. It's even better than old fashioned paper. It even allows a page marker, so you can easily return to your spot after looking up the references at the end of a paper.

Excellent and Easy

I am a lawyer and need to review and organize a lot of documents. IAnnotate is very simple to use and a pleasure to work with.

Major Crash twice a year

Dec 8, 2023 No improvement in the last 17 months. This is disgusting.
July 20, 2022 This app continues to crash. I have not been able to add documents. And worse I can’t get access to any of my files I saved. I can only hope iAnnotate will up date this app to fix this major issue asap. I have not been able to access any of my files for two months. When it works it’s a great app. But it is very un reliable. Twice a year the app degenerates to a point where I have to delete the app from my iPad and reinstall it. All my files (3.5GB) are available, but I have to open each file to make it available when when I’m away from home and WiFi. This takes at least 16 hours. The degeneration happens in two steps, first It does not allow me to download a new PDF document. Then two weeks later I can’t even open the app. This has been going on for years. I love the app when it’s working, but I’s fustratating to experience “The Major Crash” twice a year that takes 16 hours to fix. John F It has happened again (April 21, 2019) I also back up on the OneDrive app where I have over 5GB of data stored with no problems. I have been keeping the amounts of files on iAnnotate as low as possible, But it’s crashed again with 1.27 GBs of files, and as usual it’s at the most inconvenient time. I like iAnnotate for the highlighting feature, but apart from that the reliability is god awful. John F
