Annotate, highlight, and handwrite on PDFs? seamlessly across your phone, tablet, and desktop with real-time cloud sync.
Added Apr 23, 2026
Medium opportunity (62%)
Students and professionals who read PDFs? across multiple devices struggle to find a single app that handles rich annotation (highlighting, handwriting, sticky notes, stylus input) while keeping everything in sync via cloud storage. Most apps are either bloated and complex, too limited in annotation features, or require cumbersome import/export workflows instead of editing files in place.
A focused PDF? reader and annotation app that supports multi-color highlighting, handwritten stylus notes with collapsible sticky notes, live OCR? for handwriting, and tabbed multi-document browsing — all synced in real-time to Google Drive, OneDrive, or Dropbox so files are always current across Android, iOS, and desktop. Files are edited in-place in cloud storage, eliminating import/export friction.
Tablet and stylus adoption is surging (Samsung Galaxy Tab, iPad, Lenovo with stylus) among students and hybrid workers, creating a growing user base that demands desktop-grade PDF? workflows on mobile. Existing leaders like Xodo have declined in quality, leaving a clear gap in the market.

I use this mostly for organizing my study notes and project planning. The ability to sync everything to the cloud is a lifesaver since I often switch between my phone and my laptop. The templates look great, and I love the feature that turns a basic outline into a full map instantly. It’s much easier to use than other mapping apps I’ve tried
Absolutely a dream app to work with, there is nothing it cannot do it performs perfectly. Cannot recommend this app enough worth every cent.
this app is very much helpful for my college journey and it's very budget friendly so this is best for lifetime access but this would make everything fantastic if they the real-time beautification of handwriting instead of using the textbox
