Premium
Take handwritten notes naturally on your Android tablet, phone, or Chromebook supporting Android apps! With Squid you can write just like you would on paper using an active pen, passive stylus, or your finger.
Easily markup PDFs to fill out forms, edit/grade papers, or sign documents. Import images, draw shapes, and add typed text to your notes. Quickly select, copy/paste, and move content between pages and notes. Organize your notes within notebooks and increase your productivity!
Turn your device into a virtual whiteboard or give presentations in a class, meeting, or conference by wirelessly casting to a TV/projector (e.g. using Miracast, Chromecast). Export notes as PDFs or images, then share them with others or store them in the cloud!
Squid is vector based - keeping your notes beautiful at any zoom level and on any device. You can erase entire letters and words quickly with the stroke eraser tool, or just parts of words with the true eraser tool. The selection tool allows you to change the color and thickness of your handwriting and even resize a drawing whenever you want without any loss in quality.
Squid takes special advantage of active pens on capable devices to provide natural, pressure sensitive handwriting. Just write with the pen and erase with your finger!
Squid is designed to be both powerful and simple to use, allowing you to take notes quickly and efficiently.
