Ratings and reviews

I am looking for a better and perfect app that I can use for digital journaling until I see this app. So far, I like the features that it offers, especially the hyperlinks. My only concern here is the sticker feature, since I am using it for journaling, I want it to have a feature that you can import your own stickers. I also want it to have an adding tab feature like other taking notes app to make it lot easier to copy image from other PDFs using lasso tool.

I'm happy with this app! It's very comprehensive and has a great price for a lifetime subscription. However, I'm wondering if there are plans to improve the sync feature. Currently, the auto-sync only supports .jnote, and it would be better if it also supported .pdf to avoid the need for exporting each file separately.

Hi, I love this app, but one important feature is missing : I want to see and edit my files on desktop too. So, let us work on editable PDF files. I mean, when I made changes on PDF, I want to automatically save it as PDF file. As can be seen from export option, there is already editable PDF export option. Just don't force us to use jnote files.
