Talking [Q] Moto G LTE, SD Card questions ?

I`m one of the people that ordered the moto g lte version of of amazon and for $19 more, i would say it worth it. LTE and a micro SD card slot (plus it comes in white and black) I plan to root my device and get a 32gb SD. Now the moto g has 8GB internal memory and i want to use that for my "important apps" then use the SD for my games. Is there an app for doing this ? i prefer not to do it on a computer since im no ubuntu pro :/

TL;DR Is there an app for sorting where you want your apps to install (internal or sd memory)
