About this app

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.

It's mostly good. It can be difficult to use. For example, I don't know how to delete a note. Its also kind of clunky: for example to erase anything you have to open a pop up, switch to eraser, erase item, open another pop up, switch to pen, etc.. it's a lot of steps for something that should be quick and painless. Over all though it's def one of the better note takers/doodlers I've used.

This app does NEARLY everything I need. If I need to take handwritten ONLY notes it's amazing, but if I want to do a mix of handwritten and typed notes it's a mess and basically unusable. If I click with a touchpad I don't want to draw, I want to insert a text box. If this was an option this application would basically be perfect. Only thing after that is to support more formatting and keyboard shortcuts for said formatting.

Exvellent note taking experience. I use this on my Samsung chromebook with the S-pen, by far the best feeling notes app on android. I subscribed to the pro mode for over a year but unsubscribed because the PDF functionality is lacking. The fact that I couldn't highlight pdf text for copying made multitasking a pain. Also the way text insertion works uses too much wasted space on big screen tablet devices. If those two gripes were fixed I would happily support the developers by subscribing yearly.
