SimpleEdit is a plain text editor designed with SwiftUI for iPhone users. It allows users to open text and compatible data files encoded in UTF8 directly from the Files app. Additionally, the app offers a view-only mode for data detection, enabling the identification of links, phone numbers, and addresses effortlessly.

One standout feature of SimpleEdit is the rewind button, which allows users to revert files to their original state. The app supports dark mode, multiwindow functionality, and state restoration, providing a seamless editing experience. Users can customize the font family and size for editing purposes, and choose fonts using the system font picker, displaying fonts installed in the Settings app.
