We don't think we need to explain the Hashtag App TOO much to our clever little readers. It's basically a mobile app that allows you to track... you guessed it... hashtags. However, you're not just constrained to Twitter, you can track them in a simple feed from Instagram too.
The app is ideal if you're at an event, work in social mediaz and want to monitor a particular client or competition while you're on the move, or if you just have a weird obsession with something, like #sea or #puppies, then you'll ALWAYS get to peek at new content about it. Weirdo.
The app is really simple, you don't need to be logged in to Twitter or Instagram to use it, you just enter your hashtag of choice and pull down to refresh the content. If you want to look for a new one, just start again. Easy.
Available from the app store for free.
