I can’t comment on your particular client, but I suspect most of them should support it in some form.
It looks like Thunder is available for Android and iOS. I dont really use it but I do have it installed, so I took a look. It has a “user label” function that looks pretty similar and is added through the same basic process.
Note that I am very much not an expert on Lemmy and even less so on anything Apple, but I bet a way can be found! And if not you always have the option of submitting a feature request to the developer of whatever app you do use.
As for what they are, the green text in my screenshot.
How depends on how you access Lemmy. In my client, Connect, I expand a comment, tap the three dots to the right of it, and click “add user note.”
Aww, sadly I’m iOS and not Android, so I can’t use Connect nor I guess user notes.

Good luck!
