Why not just use Markup
Markup is for scribbling, not filling out a form
The Markup tool built into Files and Mail is fine for dropping a signature onto a single page, but it doesn't recognize checkboxes or text fields, and there's no way to position things precisely before you're committed. PDkef fills real form fields directly and lets you place your signature exactly where it needs to go.
