Text Case

Text Case is a text transformation utility, that can be as powerful as you make it, and accessible throughout iOS.

Flows

These are customisable combinations of formats, that can be put together to create more complex and personal text transformations.

Tons of Formats

There's over 60 text formats to choose from in the app, from simple ones such as Base64 encoding, to fun ones such as Mocking SpongeBob or Clap Case, various Markdown formats, and even some more complex formats which allow customisation such as replacing all occurrences of a string, or adding a prefix/suffix.

Services

All formats can be accessed on the macOS app via the Services menu.

They apply the format directly to the selected text, which means no extra action is required. And since they are services, you can add a custom keyboard shortcut to them!

Unfortunately, I do need to add a caveat to this: It appears there is an issue with Catalyst based macOS apps where they do not support app-based text replacement services, where the services work up to the transformation happening, but the Catalyst app not taking the result and replacing the text.

Share Extension

It comes packed with an action extension that lets you select text anywhere in iOS, tap the Share button, and then you’ll find the “Convert Text” action. This will show you a preview of all available formats, and a simple tap on one of those will copy it to your clipboard, and you’ll be returned to the original app.

You can customise the extension to show just the flows you've created, the standard formats, or both.
