Twitter hashtag notifications on Watch

I use Tweetbot but I’ve never had notifications turned on for even my iPhone.

Next week, I’m going to be at a conference and I want the ability to get notifications of a specific hashtag sent to my phone and watch.

Can anyone recommend a twitter client that does that? As far as I can tell, I can’t do this using Tweetbot.

Is it important that the notifications be instant? If not you could do this with IFTTT

Interesting but yes, it needs to be instant.
