Text Workflow is a text transformation app for iPhone and iPad.
This is the iOS version of Text Workflow Mac app.
Just give some text you want to transform, and then choose from text transformation actions or create sequences of actions (the app call them "Workflows"), so you can transform input text and get the results. For example you can give a list and choose the "Number lines" action to add the line number as prefix on every line.
You can use simple actions to transform your text, or combine actions to create complex workflows. You can save your workflows so you can use them whenever you want, like your own custom macros.
Please check the overall behaviour of the app. Check if actions and workflows works as expected.
