iAnnotate 4 — PDFs & more

I really wanted to like this app because the workflow is actually great when it works. Highlighting feels smooth and it’s easy to stay in a rhythm when prepping large documents. But I’ve now run into the same issue multiple times and it’s a dealbreaker. Everything looks consistent while I’m working in the app, but when I export to PDF, the highlight colors change in intensity. Some sections come out darker or lighter even though I used the exact same color. It ends up looking inconsistent and unprofessional, and there’s no way to catch it until after export. On top of that, the app crashes when working on larger files, which makes the whole thing even more unreliable. I use this for professional work where consistency matters, and I can’t risk something like this happening again. I didn’t have this issue with other apps, so it’s really disappointing. If this gets fixed, I’d absolutely consider coming back to it. But right now, I can’t trust it

Your app refuses to convert Docs from Canvas. It just sits and refuses to accept the file. It will convert them from Google Drive, but I should not have to download papers into another app just so that your software will finally do its job. I have reported the conversion bug problems for .docx files before, and your team gave a less than useful answer. Please actually fix the issue this time. I have used your app to grade for over a decade now, and I would rather use it than Speedgrader or other tools, but this problem cannot persist. If it does, I’ll have to go elsewhere. My students deserve better than consistently buggy software.

It crashes all the time since the update. ipadOS 26.1. Every time I reopen the app, all tabs are gone. I will try reinstalling a fresh copy. I have been a happy user for 15 years. A reinstall was ineffective.

I've used iAnnotate for my business proofreading for court reporters for over 10 years. From the ability to custom create stamps for mark-up to ease of use to fast, responsive support, this app is perfect in every way. Love it, love it, love it.

I’ve tried every PDF app out there and I keep coming back to iAnnotate for grading papers. It is by far the best and most flexible app. The iPad is a perfect tool for providing feedback on student writing and iAnnotate is the best app for the job.

I’ve been using this app for years. It really does everything I need it to do. Great annotation. Easy to navigate. Worth the purchase.

I use this almost EVERY day for my clinic, and my post-graduate work.. Google drive no longer syncing!! Please fix this issue!! Will remove review once fixed! Please help!! It’s been several months with no response or support.

I have been using this software for years across multiple devices, with all sorts of documents. When I need to get work done, form submitted, notes taken, the software does it. And, it does it with ease!

I’ve used iA for several years. I like that there are separate toolbars you can toggle between. (I use different toolbars for different projects. ie: Paperwork includes text boxes, stamps for signatures, highlighters & basic pens. Notating Books includes different highlighters & pens, eraser and images, and bookmarks. File organizing includes +/- pages, bookmarks, images, etc.). There are some annoying quirks that I can overlook, evident as I have still selected 5 stars.

I’ve been using this as a professor for years, and it has gotten me through two books and countless articles. When I’ve had tech troubles, I’ve always gotten quick responses. I appreciate that they haven’t complicated it endlessly in the name of small improvements. One of the best purchases I’ve made.
