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.

On a Pixel Slate, this is a great app. There are just a couple of things that are almost deal breakers for me. I'm sure most of it is user-error, but I cannot get the palm rejection to work for the life of me. As I draw with the stylus, it's constantly trying to multi-task, zoom or other things. I wish there was a quick and easy way to turn on palm rejection. I also wish there were more pen types like in INKredible. The other big missing feature is the ability to back up to Google Drive as a cloud option. That seems pretty reasonable since, as I'm on an Android device I will clearly have a Google Drive account. Having used both iOS and Android tablets, I think this is the best one on Android, but I still feel like GoodNotes on iOS is the best, overall experience and has some great features Squid should take a look at...

Good app and good stylus support, but the lack of sync makes it much less useful than other note taking applications. Unfortunately, I'm cancelling my subscription since the developers have been "working" on sync for years now, which is supported by many other note taking apps for free. As much as I like the app, it doesn't make sense to pay for something that's missing a major feature that its competitors have.

Thanks for your feedback, Clay. We understand your frustration. We want to make this happen just as badly as you do. We are discussing how to make this work with the Google team in light of the recently announced changes to Drive. It is a top priority for us. Please feel free to email us at help@squidnotes.com if you'd like to discuss.

I've been using Squid every day for two different classes, so about 6 months total, and it's really a great app. I can only really think of some minor suggestions for improvement, such as sync across devices, and the ability to add to remove elements after selecting them with the selection tool. And it would be nice to have the ability to lock some items in place, so they don't get moved or selected accidentally later. I often make tables and being the force them into the background after drawing them, similar to how an imported PDF functions, would be nice. That's about all I can think of for now. But this app is so much better than all the others I've looked it, it's hard to complain too much. I especially like how it works so well with my S Pen to suppress any contact my hand makes from disturbing my canvas.
