Maybe I'm missing something, but on desktop it is non-trivial to find out if someone has replied to one of my comments. I have to click on my profile, click on "comments", scroll down and look through all the various comments I've made... if someone replies to a comment which has already fallen off the first or second page at this point I basically won't see it.
The situation on mobile is even worse. My phone runs Android, so I use Materialistic (https://play.google.com/store/apps/details?id=io.github.hidroh.materialistic&hl=en_US) to browse HN, which has been the best client I've found to-date (and I actually prefer it to the web interface on desktop), however it doesn't even show replies to comments I have made. I have to go back to the original thread and then scroll through hundreds of comments to find the one I made previously to see if anyone has replied to it.
Is there an alternative front-end available which adds this functionality on top of HN? Am I just missing this functionality somewhere, or are others really manually going through their comments all the time?
