CPC is just the wrong model for Facebook. It turns into "spray and pray". In this case, nobody is looking for a personal budget app, it just shows up uninvited. Whereas with Google, we know someone is likely looking for it when the ad appears.
That's true. Since people spend a lot of time using Facebook (i.e. as a "third place" with no specific search intent), I would guess that brand advertising, brand-awareness marketing, and especially targeted ad remarketing would be their sweet spots.
