Irregular Expressions

Irregular Expressions is an open-source custom virtual keyboard for Android. It lets users add decorative text styles in places where standard text formatting is not normally available. The keyboard is intended for people who want to vary the appearance of messages, social posts, and other typed text.

It provides more than 30 styles for changing the visual form of characters. These include Gothic or Old English lettering, small capitals, upside-down text, and script-style writing. The styles can be used in text messages, tweets, Facebook posts, and other areas that accept typed text. Its purpose is focused on character styling rather than general document formatting.

Irregular Expressions belongs to the System Tools category because it changes how users enter text on an Android device. Android Oreo, version 8.0, or a later release is required for the full selection of styles. Some characters may not be supported on older Android versions, so the available result can depend on the device’s software.

MirrorNest distributes the official build directly from its own storage. The mirrored package is scanned for malware before it is published. This distribution setup gives Android users a catalog copy of the official open-source software while keeping the product’s platform and licensing information clear.
