About this app

New: We partnered with Google to bring incredibly fast, low-latency ink to Squid on the Google Pixelbook and Samsung Chromebook Plus (with Chrome 62). See the difference: https://youtu.be/Oc66T_e7xwU

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.

I've been using Squid for about the past year to make grid maps for a text-based game (a MUD), and have been very pleased with the results. Minor requests: considering how many files I've accumulated now, it would be nice if the app had a search feature. Additionally, if you had the capability to type in the line/text size instead of using the meter bar, you could quickly get the thickness you want than to keep jumping back and forth until you land on your desired results. Thanks for the app.

The app is wonderful in so many ways, BUT! Please enable scrolling between pages, both in regular squid notes and in imported PDF's, instead of having to click the tiny arrow in the upright corner. If that feature is enabled this becomes a five star review. Another cool feature would be to be able to rotate and flip objects that you've "marked" with the square or lasso. Thanks!

Great app! My preferred note taking and mark-up app. Please add this feature: Different default zoom levels for portrait and landscape device orientation (e.g. Portrait: Fit Height; Landscape: Fit Width). This would allow me to easily view full pages, and also to easily mark them up as well. ------------------------------------ Thanks for your reply. Btw, I get a CloudFare error when I go to that site. [2022-Oct-02]
