There are hundreds of thousands of iPhone, iPod touch, and iPad apps for just about everything -- so how come the one you need, the one you know just has to be there, is so hard to find? Enter TiPb's new weekly feature where staff and readers alike sort through the App Store and help you find just the right App for That. This week, @Bitterblade asks:

I want a twitter app that syncs unread tweets between my iPhone and iPad.

We're going to switch things up a little this time, and instead of recommending a specific app, we're going to take a look at a service that can be used between multiple apps. To find out what it is, follow along after the break!

Tweet Marker is a web service that marks your last read tweet. As long as you have the service set up on at least two different Twitter clients, you can free jump between the two apps without losing place of which Tweet you read last. Just enable the feature in the apps' settings, and you're good to go!

Here is a list of Twitter apps that support Tweet Marker:

Bonus: Twitterrific also has a Mac version [$4.99 - Mac App Store link] that supports Tweet Marker. The Chrome extension WebMarker does as well.
