About Squid
Squid – Take Notes & Markup PDFs provides a digital substitute for paper to take notes with your Android device. Users of this app can mimic the physical experience of taking notes with pen and paper by using their finger or a stylus to write on the app. The app uses a vector graphics engine to render lines and text, keeping strokes sharp and clear at any zoom level. It also allows users to adjust the color and thickness of strokes after the strokes have been made, giving users flexibility to keep their notes legible at different zooms. This flexibility is essential for students and professionals reviewing diagrams and/or information at various sizes (legibility).
The application goes beyond simple note taking, enabling interaction with various external documents and digital media. The users can directly upload PDFs into the application for various markups, making it the central location for review of all documents. Once the document is uploaded to the application, users can choose to highlight any portion of the text, add notes in the margins, underline text, etc. It simplifies administrative tasks like completing digital forms and adding signatures. Unlike a traditional digital form, a printout has to be signed, scanned and uploaded back. The application simplifies the task and eliminates the paper touch. Being able to annotate a PDF gives the ability for the application to integrate feedback for various documents like contracts, academic papers, or blueprints. The application allows users to edit a document, save it, and share it for review. Users can print the edited document. The application preserves the original document layout, and incorporates the new hand-written changes.
This application gives users tools to create structured data within a note. The tools are similar to those found in a traditional drawing application, allowing the user to create structured content, in addition to text. The user can insert an image from their device to the note. The user can write or draw on the note and rapidly relocate, copy or move parts to other locations in the same or a different note. The layout supports modular note taking. This idea with note taking allows the user to organize and unclutter their thoughts as they write, draw, relocate or remove parts to aid in organizing and restructuring their project and thoughts. Users can organize notes representing different data (i.e. math problems, diagrams, annotations) to help keep their notes structured and organized.
The application is useful to students and professionals in education and business. A whiteboard is useful for capturing notes, and this application takes it a step further by allowing users to digitally capture notes and export the notes to a digital format. A user can project the application to a screen by wirelessly connecting their Android device to the projector. With this functionality, a presenter can capture notes on a screen in a classroom or board room. Notes can be captured digitally and saved for posterity. Photos of the whiteboard are a thing of the past, as the presenter can save the digital file of notes.

To ensure portability of data, the application provides multiple export formats. In addition, the application supports a variety of Cloud services. PDF and PNG are the two export formats that enable Notes to be published in high quality. Notes in PDF or PNG format can be posted to publicly accessible Cloud services. The application supports various Cloud services and employs a secure authentication procedure to back up users’ data. This feature is essential for users wanting to move their data to a different device. The users can have their data available in various locations. The users can also gain access to their data if the local hard drive fails. The application employs a secure vector graphic format for notes. The sharp lines and clear text are retained even when the Notes document is viewed on a small display.
Design efforts focused on simplicity and power. This approach considers the needs of students and seasoned engineers alike. More recently, development work has been focused on improving the user experience for various versions of the Android operating system, primarily targeting Android 11 and beyond. From a UX perspective, the app has made progress in the correct rendering of PDF text for the language scripts of East and South East Asia, including Chinese, Japanese and Korean. This fix addressed a long-standing issue where users would see unsightly document formatting errors or simply see incorrect document contents. As a bonus, some restructuring of the application’s file system has resulted in the removal of erroneous, bulkier fonts, which tends to speed up application load times and reduce the size of the application once installed. These continuous, iterative development efforts allow the application to continually adjust to a multitude of user needs and hardware.
