I am using Inline Tag Navigator (disclaimer: I'm the author) on desktop and mobile to manage inline TODOs. it has a panel for interacting with tasks (simple checkboxes, or ones inspired by [x]it!), and can additionally generate summary notes in various formats (including a recently added kanban view). the format that I personally prefer is very similar to Inline TODOs' confluence style.
Inline Tag Navigator supports customisation with regexes, so you can define what an inline tag is. you could probably hack it to find all todo.txt lines for you, and list them in a note. for example, if you always use priorities, perhaps define the priority element as your tag. alternatively, if you always have a due date, use it (or use both).
