4月1日的Scratch Pad应用程序分析

Scratch Pad is a simple whiteboard app. You can use it like you would scratch paper. ## Features * Full screen, zero ads * Pan and zoom using two fingers * Quick Clear button * Simple and minimalist ## UX Considerations * Infinite edge-to-edge canvas that expands as you pan and zoom * Minimal, translucent action buttons * Drawing from left/right sides won't trigger the back gesture * Rotate between portrait/landscape modes and your drawing will rotate with you ## Motivation for app I wanted a simple whiteboard app to work out math equations, but couldn't find one to my liking. So I made my own.
