What could make such an app "stand out"?

The app already does a good job of standing out with its main premise and I doubt there are enough other stand out features to add for the niche. The problem really lies in the monetization focusing on the table stakes features up front instead of the stand out features after a while.

Should be free first of all, HN is free after all and with it's old tech it is still working well and is also friction free. I've seen plenty of show HN:HN and most don't have traction because the original is just too good. It's probably one reason why it withstood the test of time and why we still have a community here.

I think it's less "too good" and more "$0 but been around 18 years so why bother with any alternative for >=$0 which has been around for 2 months. Also, why do I trust you again?". I.e. "not bad enough".

Or it’s that every platform like this that does a major upgrade to the UI is awful. They are almost always driven by people looking to increase revenue at the expense of the user experience. The users hate it and leave in mass. Having seen this pattern time and time again, I don’t know why sites keep doing it, other than then obvious “investor pressure.”

There seems to be an inverse relationship between the spend on development and user experience.
