Best App Support EVER

I can’t believe how helpful these developers are. Facing a tight audiobook recording deadline, I ran into a strange issue with a document which wouldn’t take any markings - the publishers hadn’t bothered to pass the .pdf through OCR, so the pages were like .jpgs. The iAnnotate team responded immediately to my panicked emails, and worked patiently and tirelessly with me over a few days to adjust my document so that it finally worked.
iAnnotate is the industry standard for recording audiobooks for good reason, as the app provides fantastic resources for marking up a script. Their app support, however, raises it to a whole new level. Thank you, support team. You all ROCK.

I have been meaning to write a review for sometime. I use the app to digest pdfs, mark them up, highlight material, reorientate pages. I use it in a court room environment. Out of court I am reviewing and preparing for the hearing. In court I use it to present the case. The ability to move around within the case is excellent and I can switch between witness statements exhibits and reviews at the tap of a virtual button. The ability to search within the PDF is very useful to.

When not using this for Court work I use to digest other pdfs that come my way. Again the facilities within app are of great use.

Would I recommend this app to others who have need to digest pdfs? Absolutely.

On odd occasions I have had an issue when Apple have updated their software which has caused issues but I have found the developers working on a fix or workaround. They are very responsive.

Highly recommended.

Worth every penny

I’ve had this app (or its previous version) for around 7-8 years now. It’s absolutely brilliant: saves lots of filing space (just file electronically), works really well with the Apple Pencil (though doesn’t make bad handwriting better, sadly ;o)), and is very intuitive... until I had an issue today that I could “intuit”... and discovered that the support team’s response time is extremely fast. Highly recommended.
