iPadで使用すると検索機能が使えない

Response from developer

Thank you for bringing this to our attention. We’re sorry you’re having trouble searching with Japanese keyboard input. We’d like to look into this further. Please reach out to us at help@folia.com so our team can investigate the issue. Thank you for helping us improve iAnnotate!

Ótimo

Excelente app para trabalhar com roteiros de cinema. Sinto falta apenas das anotações não serem atualizadas quando o arquivo é substituído.

Response from developer

Thank you for the great feedback! We’re glad to hear iAnnotate works well for your screenplay workflow. We also appreciate the suggestion about carrying annotations over when a file is replaced. That’s a helpful use case for our team to consider as we continue improving the app. We’d love to hear more about how you would use that feature. Please write to our team at help@folia.com

Very useful

The app is really good. The only small point I have is that the tool bar at the side obscures part of the document when it is active. I use it to review pdf slide decks so this often hides the slide number which makes it more difficult to write up the review afterwards.

Response from developer

Thanks for the thoughtful feedback. We’re glad to hear you’re finding the app useful overall. We appreciate you pointing out the issue with the side toolbar obscuring parts of the document. We’ll share this with the team as we continue improving the reading and annotation experience. If possible, please reach out to our support team at help@folia.com with a screenshot and any additional details so we can better understand the issue. Thank you again for your feedback and support!

Loading Files to slow or not possible

I actually love this app and I use it a lot. However, it happens so often that when you need to source and open a file from iCloud the app just doesn’t show any of the file / folder structure and needs way too long if at all to open the document

Response from developer

Thanks so much for the feedback! We understand how frustrating the iCloud file picker experience can be when folders don’t load properly or documents take too long to open. Your feedback is genuinely helpful because it helps us prioritize where we can improve the app. We’ll investigate the iCloud issue further, and if you’re open to it, feel free to reach out to help@folia.com so our support team can gather more details and keep you updated. Thanks again for taking the time to share this with us.

INCONSISTENT AND CRASHES

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
