Like it or lump it, there’s little question that Klout is the standard many employ for measuring social media influence. The new Klout for iPhone version 1.5, which debuts today, adds some significant functionality for avid users of the service – features that have been added as a direct result of the feedback the company has received since the first version debuted in April.

Changes include the addition of “Swipe to +K,” which lets you endorse other users’ influence by swiping your finger across one of their Topics, the same way you unlock your phone. A new Search function has been added that lets you enter any Twitter handle to find out that user’s Klout score. And a “Logout” button has been added to make it easier to switch between multiple Klout profiles, so if you’re using the app to track personal and professional identities, you’ll have an easier time of it.

Klout’s Stephen Hood says in a blog post that more is on the way, including the ability to connect other social networks to your Klout profile using your iPhone.
