Read full descriptionHide full description
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. Enjoy the world of ambigrams with AmbiPad.
Mojiatume

Build your own visual dictionary of distinctive lettering. Mojiatume is for lettering artists, designers, and anyone who notices type in everyday life. Save lettering from street signs, shop logos, photos, and social posts. Take or import a photo, straighten its perspective, select character areas, and save each design separately. Search by character, tags, or radicals, and revisit captured locations on a map. Keep the original photo alongside each entry. Create a separate portfolio for your own work, with sketches and process images. Importing dictionary files is free. The free plan supports up to 2,000 collected characters. A one-time purchase removes that limit and unlocks dictionary export, a home screen photo widget, and additional app icons. Creating collections beyond the free limit requires the one-time purchase. Monthly support plans help fund development; available extras depend on the plan and remain active during the subscription. A commercial-use license is required only when the exported dictionary data itself is sold for a price. Free sharing and free bonus distributions do not require the license. See the in-app commercial-use policy. Before saving or sharing images and lettering, make sure you own the rights or have permission.
