I would have happily paid for it and would 100% pay for a version that worked on Mac as well as iPad/iPhone. Most unusually in the world of apps it does something that seems to be unique - no other app offers this straightforward functionality. I live in fear of it being withdrawn! ### 5/5 — Perfect app for goodnotes users *2025-12-02, version 1.3.6* god bless ### 5/5 — Perfect for importing Slides/PDFs into Goodnotes for annotation. Works fluidly, and for free. *2025-01-04, version 1.3.6* This app is very simple to use and works simply as intended. It solves the problem I had of wanting to annotate my PDF slides or documents for school and class but not having enough space to write, such as using MarkUp or when importing PDFs into Goodnotes 6. Now, I can add exactly how much blank area or margin I want all around the page and annotate the PDF without running out of space. ### 5/5 — Recommended feature: ruled lines *2024-10-01, version 1.3.6* This app is great! One feature that would be great is the ability to add fill layers to the added margins. If I could make the added margins lined, it would be easier for me to take notes in the margins. This is a great app, thank you! ### 5/5 — A lifesaver for me as a student! *2024-02-25, version 1.3.6* This app does exactly what I was looking for, which adding margins to my pdfs so I can take my notes in the same file! It’s stable, maintained by this angel of developer and most importantly it’s FREE. Thanks soooo much! ### 5/5 — THANK GOD THIS EXISTS! *2024-02-23, version 1.3.6* I just spent two hours of my life trying to use free trials of GoodNotes and LiquidText and neither one of those helped like this app did! I’m so happy that I found an app that is able to adjust the margin size of my long PDF files so that I can further take notes on each individual slide. Honestly surprised that this was free. Hopefully in the future the developer can add a note taking feature so that I don’t have to transfer files from here to other note-taking apps. Nonetheless, thanks for putting this on the App Store! A real life saver for students who like to take notes on the side of the file. ### 5/5 — Amazing! So useful with Apple Pencil *2024-01-19, version 1.3.6* This has taken my pdf annotation with apple pencil up to a whole new level as I can finally add significant margins in my pdfs to annotate and handwrite in. I would gladly pay 2-10$ for this. Hope others catch on to how useful the app is. Thank you for maintaining it and making it free. ### 5/5 — Best software ever *2024-01-07, version 1.3.6* Thank you for this amazing piece of tech. I annotate a lot and this really helps me.
