Is CubeDesk Free?

I have created this account solely to ask this question. My friend introduced me to CubeDesk, and honestly I like it more than cstimer(just a personal preference.) I've used cstimer since I began cubing but the UI of CubeDesk honestly seemed more better, but when I heard he pays 5$ a month for it I got my hopes crushed. However I saw someone online say its free?
