UTF eight is great
Curtis is a simple utility for editing plain-text scripts, code or text. It is not a fancy IDE, word processor or markdown editor. It is proudly, purposefully, stupidly simple.
Curtis is a document-based app. While there is a familiar left column list of your files, they are also accessible in the iOS Files app. They aren’t trapped or hidden, and can be viewed or edited with other software. There are no server or cloud container settings to configure.
