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. ## 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. ## Siri Shortcuts Support ## You can access all flows and formats inside the Shortcuts app, which come along with dedicated actions for the more complex actions such as Replace, Remove, and Add Prefix/Suffix.

Verdict

The call

The clearest difference is ads: Text Case at none against Castform's shown. Text Case also leads on iOS requirement (16.0 vs 18.6). Castform's advantage is update cadence (fortnightly vs every 2 months). On price, in-app purchases and device support there is nothing between them.
