A reply or a mention on nostr can buzz your phone.

The push notifier now watches kind 1 for the user's pubkey beside DMs and
zap receipts, and pushes who, what, and an excerpt. The worker shows
"New reply to your post" or "You were mentioned" with the text, and a tap
lands in the Notifications list — as ?open=notifs when a window has to
be opened, or as a worker message when one already is. It has its own
switch, "Replies and mentions on nostr", in Settings → Notifications,
on by default like payments and DMs.
