• add a signature pad to a checkout or contract form
• export a drawn signature as a bitmap image
• export a signature as an svg vector
• let users sign delivery confirmations on a tablet
• customize pen color and stroke width for signing

When to choose

• you need smooth, natural-looking signature capture on Android
• you want vector (SVG) or bitmap export of signatures
• you want a drop-in custom View with configurable pen attributes

When to avoid

• you need signature capture on iOS, web, or desktop
• you need typed or biometric signature verification
