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.

Best note taking app available on android, but still a long way to go. Better documentation of gestures would be great, as would the ability to open notes side by side like on Notability. I also wish I could rotate drawn text, and that it was possible to select and manipulate parts of imported pdfs without leaving the app. Rotating pdfs would be great too. I do quite appreciate the ability to import pdfs, change color and thickness of selected strokes, and export files so easily.

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.
