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 like a lot about this app. However, I wish I could change the background colors for my notes, while maintaining grids/layouts for better contrast. I absolutely HATE that the most useful (to me) additional features are locked behind a subscription, I would be much happier with a one-time upgrade fee for all "premium features". For some reason, importing PDFs is a feature that can be unlocked with a one-time fee, but not additional layouts? Wack.

Hi Dom - Thank you for your review. The premium paper backgrounds are the one feature we have reserved for our subscription users. We're sorry about that! However, with the PDF Import feature you can essentially import any other background you would like to use in lieu of our background library. Reach out anytime at help@squid.app.

I like the app because it's useful. It has the best pen to screen input on Android and ChromeOS. However, the app could really really really use a new interface. The app looks like something out of 2017. It would also like to add that a feature to change the theme would be nice, cyan and orange really isn't a great color combo along with dark mode.

Original review: Constantly freezing and crashing. 1 star. Update: After sending probably somewhere between 30-60 crash reports almost every time the app froze(which was at minimum 5 times a day), something miraculous happened a couple of months ago; the app stopped freezing/crashing!! As of a couple of months ago, it's working SO much better. It freezes maybe once every two weeks but after a minute or so unfreezes. I realized I had forgotten to come back and update my review. Thanks for fixing!
