Most likely it is possible, but You'll have to figure out how to do it Yourself as Google search did not come back with any useful results. In order to access any hardware on mobile phone (I assume that's what You mean by mobile) You have to have good understanding of OS managing that hardware, then You can tap into it. Most modern smartphones have good SDKs to enable relatively easy app development, all You have to do is learn how to use those SDKs. To point You to the right SDK You have to tell us what mobile phone You are talking about. Also, in my opinion, using accelerometer with microcontroller is much easier than developing app for smartphone and separate software for remote microcontroller.
