Rank Tracker for mobile search?

Hi guys,
I am considering of making a free Rank Tracker for mobile search. The rank tracker would be almost identical with my regular search Rank Tracker but it would be an independent application for mobile search results (not both). Would people be interested in such a software? Or would people prefer an application combining both?

Well, it really depends on a website but mobile traffic lags behind other types of traffic in most cases. Anyway, you can check the device people use to access your site in Google Analytics. And just use common universal rank checkers to check your ranking progress on your keywords.
