Save recipes in different file formats

I feel that some sort of mobile friendly option is 'a must have'. A dedicated mobile app would be preferable, but I got brainstorming if there are other easy to implement options that could be good enough.

First off, I have to admit that the web interface looks nice within a mobile browser. That being said, personally it is impractical. I want my password database and 2FA codes to be on septate devices. This makes it hard to access recipes on the go without a laptop.

Since the app already uses files as its back end, could there be some ways to access recipes on mobile. Here are some ideas I came up with.

Prettyprint json:
Use a more human readable json format. The file extension would also need to get changed to txt to read the recipes within the Nextcloud files app.

Markdown:
Add markdown files for each recipe when added or edited. Markdown is fully support within the Nextcloud files app and is easier to read than prettyprint json.

PDF:
Like Markdown, a PDF for each recipe could be created. A third party PDF app would be needed. There is already some code written to create PDFs.

@mrzapp, I am curious on what you think of these ideas or if you view them as out of scope.
