Yes, Squid fully supports active pens on compatible devices like Samsung Galaxy Note series with pressure-sensitive input. On devices without active pens, you can write with your finger or passive stylus with full app functionality. Performance is optimal with active pen-enabled devices.
Yes, premium users can import PDFs and annotate them with pen tools, highlighters, erasers, and text. Mark up forms, grade papers, sign documents, and add sketches directly to PDFs. Free users can view but not import PDFs for editing.
Premium subscribers can automatically backup notes to Google Drive, Dropbox, or Box. Free users can manually backup notes locally to their device storage. All backups preserve the original Squid Note format for future editing.
Currently, Squid is available exclusively on Android, Chromebooks, and Windows devices. There is no official iOS version available for iPhone or iPad, though similar functionality can be found in other iOS note-taking apps.
Free users access blank, ruled, and graph paper backgrounds. Premium subscribers unlock additional backgrounds including math grid, engineering paper, music staff, sports templates, daily planners, and various premium designs for professional use.
While Squid doesn't offer real-time collaborative editing, you can export and share notes via email, Google Drive, Dropbox, or Box. Recipients can view shared notes but would need Squid installed to edit them directly.
Squid requires only 23.44 MB of installation storage on Android. Note storage depends on your content and the number of pages. Premium cloud backup stores notes in your Dropbox, Google Drive, or Box account using that service's storage quota.
