iOS App That Delivers Push Notifications for Twitter Hanshtags Is there an iOS app (free or paid) that sends push notifications when a new post with a certain hashtag or keyword is tweeted?

I see Twitterrific can send a push notification when I get @mentioned or get a direct message, but I can't see how to configure it to subscribe to a #hashtag and push me a notification.

Can this be done with one app or multiple apps/services?
iOS apps don't work to filter based on keyword, so you would need an app that has a server side component that reads your stream continually and then sends a push notification to your device.

I would start with IFTTT - https://ifttt.com/ and then look at Pushover - https://pushover.net - if the former doesn't meet your tastes or needs.
