User Reviews

Users praise iAnnotate 4 for its powerful, intuitive annotation tools and flexible markup workflow, plus its long-standing usefulness across education and professional feedback. However, reliability issues dominate complaints: frequent crashes on large files, post-update instability, missing Apple Pencil Pro squeeze gestures, and cloud-sync/save problems that affect data persistence.
Pros
  • Powerful, intuitive annotation workflow with smooth highlighting, great for preparing large documents.
  • Flexible markup toolkit (stamps, signatures, multiple toolbars) that supports varied workflows like grading and proofreading.
  • Easy to use and navigate; long-standing, trusted app that users rely on across years.
  • Responsive support from developers; timely, helpful responses when issues arise.
Cons
  • Crashes and reliability issues, especially with large files or after updates, sometimes causing data loss.
  • Missing Apple Pencil Pro squeeze gestures, which hampers quick access to tools.
  • Cloud sync/save reliability issues, including Google Drive syncing problems and occasional saves not appearing or stored.

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.
