Animation Paper is an online application (or website) used to create and edit animation sequences. It provides an intuitive, user-friendly interface that allows users to draw, animate and edit their artwork. The app includes a variety of tools and features that make creating 2D animation sequences much easier and faster. These include the ability to draw frame-by-frame animations with a traditional animation workflow, as well as a range of effects, filters and colour adjustments. Animation Paper also supports collaboration, allowing users to share their artwork with others and collaborate on projects. The app also has an extensive library of pre-made assets, including characters, backgrounds and sound effects, which users can use to create their own animations. Animation Paper is suitable for both professionals and hobbyists, and is available for both desktop and mobile devices.

This is much simpler and less flexible than the other and, therefore, should not qualify.
