Meh

I would not have bought this if I knew that you couldn’t remove a password from the PDF file. Meaning that if I have the password I can open the PDF and then edit the PDF to remove the password this app I cannot do this.

Needs better guide

Trying really hard to use this app and like it. Unfortunately, on one computer, it scrolls vertically and horizontally on another. I cannot find any indications as how to fix this. I have searched on the Internet, I’ve searched on there website, and there’s absolutely no explanation.

I’ve had this app for several years and I have never been able to consistently use it to my benefit.

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
