AmbiPad

AmbiPad is an iPad/iPhone drawing app specialized for creating ambigrams (text designs that can be read the same way even when turned upside down or viewed from different angles).
With intuitive controls, anyone can easily create beautiful ambigrams. Just draw a single line and the symmetrical line will automatically appear, allowing you to create designs that can be viewed from both directions. We've incorporated various symmetry modes ideal for ambigram creation, including point symmetry, line symmetry (horizontal, vertical, diagonal), and 90-degree rotation.
You can freely edit lines while maintaining symmetry, cut them with the scissors tool, and move or rotate selected parts, making it possible to create complex ambigram designs just as you imagine them.
Customization options are plentiful, including four color themes (standard, inverted, blue, brown), and the ability to change line thickness and end styles. Completed works can be saved and shared in PNG or SVG format.
Supports Japanese, English, and French. Comfortable to use on both iPad's large screen and iPhone.
