Very nice app for pdf note writing in compariso with most other apps. However, many useful features are premium, like adding page, syncing across devices and cloud syncing. Besides, the homepage would be better with a simpler appearance.

The only downside I faced while using the app is that... It asks for login to open when we use the app offline Sometime this thing costs you a lot when you don't have Internet and you can't access the file you need.

​This app is truly impressive and has come a long way. To take it to the next level for professional analysis, adding robust PDF integration would be a game-changer. ​I’d love to see a workflow similar to LiquidText, where: ​Dedicated Note Spaces: Each PDF has an exclusive workspace tied to that file. ​Side-by-Side Annotation: Browse documents and write notes immediately beside the text. ​Smart Pinpointing: Link specific PDF sections to notes on other pages to trace references back to the source
