Electronic Signature is a free iPhone app developed by Kazuya Fujita that falls under the category of Business & Productivity. This app allows users to easily sign documents digitally, eliminating the need for physical paperwork and saving time. With a range of features to enhance the signing experience, Electronic Signature proves to be a convenient tool for professionals on the go.

The app offers a selection of colors and the ability to adjust the thickness of the pen, allowing users to customize their signatures. Additionally, users can choose from various line designs to add a personal touch to their signatures. The app also provides options to select different pens and an eraser, enabling precise editing if required.

With the undo and redo functions, users can easily rectify any mistakes made during the signing process. The scale display feature ensures accuracy while signing, and users can save their signatures as images or copy them to the clipboard for further use.

It's worth noting that the saved and copied signatures do not display tick marks, ensuring a clean and professional appearance. For those seeking an ad-free experience and additional features, there is a paid version called "Electronic Signature PRO" available through the app.
