Shameless plug: my app called HACK on both iOS and Android has push notifications for when people reply to you.

Reading this on HACK right now, love the app! I’ve actually ditched Octal, specifically because of this notification feature.

Hi! Is the app available anywhere outside the play store or is it open source? I don't have google play services.

I use Hacki on Android. An open source HN app, can find it on f-droid or play store :)

Sorry, no, the app is only available on play store and iOS App Store.

Glad you enjoy it!

Nice features. If I like it enough I could get the paid version.

I also just added this as a feature to https://catnip.vip
