# Squid boosts their rating with new features in ChromeOS

[Squid](https://play.google.com/store/apps/details?id=com.steadfastinnovation.android.projectpapyrus)
allows users to take handwritten notes naturally on various devices. With Squid
you can write just like you would on paper using an active pen, passive stylus,
or your finger and easily mark up PDFs to fill out forms, edit/grade papers, or
sign documents.

Squid was originally designed for tablets with active pens back
when Android Honeycomb was released. The latest ChromeOS devices with active
pen support that run Android apps are essentially the hardware they've been
waiting for, so it was easy for them to make the choice to optimize.

What they did
-------------

Squid was built for large screen devices from the beginning, but there were a
few areas they needed to focus on to optimize for ChromeOS. They added better
support for the keyboard with keyboard shortcuts, navigation, and making sure
hitting the "Enter" key closed dialogs where you would expect this to be the
natural behavior. They also added support for trackpad scrolling, which is
helpful when users are reviewing a note in Squid, and support for the system
clipboard.

The biggest and most beneficial effort was adding support for the low latency
stylus API, which drastically improved the core experience of Squid. Since Squid
is a handwritten note-taking app, stylus integration is extremely important
because an active pen provides a much more natural writing experience. Squid
users are astonished at how fluid and lag-free writing is now. With low-latency
support, the ink finally feels like it's coming out of the pen.

Results
-------

Squid users have given the app rave reviews. The cumulative average rating on
Chromebooks is 4.6☆, which is 8.5% higher than their average rating across all
devices. Over the last 30 days, Chromebooks have accounted for over 7% of
Squid's active devices and a significant 21% of their revenue!

They've also had schools start adopting Squid in the classroom, and are hoping
to expand this further in 2018 with the great lineup of new active pen-enabled
Chromebooks built for education.
