Default LED on while focusing?

Is there any camera app that uses the LED light while placing the focus? It's near impossible to get a sharp picture in low-light with my Desire HD.

There are ways to cut through this, though. I activate Tesla LED and keep it activated while opening my camera and sometimes and thus, use it while focusing. This is though not a sustainable solution; I would like a camera app that uses the LED in focus processing by default.
Is there one?
