Text Editor - Notepad

I prepared a file. You can name it , but you have to back space over the default name. The file appears in the app’s History, but I cannot find it searching for it on the iPhone. Also, I don’t see how you would save it to / retrieve it from a specific folder or to an external location. I did not use the formatting as my needs are simple. This might suit my needs if I could save and retrieve documents to/from folders of my choosing. Appears incomplete.

The method, if any, for adding to/editing a file is unclear. Saving a file presents on with a blank file name input box. The current file name is not displayed. No doubt a method exists (overwrite by giving the same file name?) but I just want to log data to txt not learn a new UI/management paradigm.
