Handwriting memo "a Paper" is a free, easy-to-use drawing app developed by PepperRetas for Android devices. The app provides a blank sheet of paper for users to scribble their ideas down effortlessly. The biggest feature of this app is the boundless drawing area, which allows users to write and draw without any limitations. The app also provides a natural writing feeling through three types of pens, making it easy to create handwritten notes and sketches.

The app's interface is simple and intuitive, allowing users to quickly start and respond to their ideas. It also provides unlimited undo/redo options, making it easy to make changes to your notes and sketches. Additionally, users can share their creations as images, zoom in and out of their drawings, and use the highlighter pen for semi-transparent markings. The app also supports landscape view and auto-save by long-tapping the Android back button. Lastly, users can choose from five ruled line types, including None, Horizontal, Vertical, Cross, and Music (staff notation).
