Review of LED torch apps for the iPhone 4

One feature of the iPhone 4 is the LED flash, which can be turned on using apps to be used as a torch. This is much better than using the screen. I think the LED flash is brighter than the one on my Nokia 6120.
I'm reviewing 3 of those apps here. They're all free:

Flashlight by GreenGar Studios (1.5 MB)
Can hide status bar and controls
Black or white screen
Strobe light
Has ads
Takes a while to start

iLights by Appmosys (89.6 kB)
No ads
Strobe light
No black screen
Strobe is slower than Flashlight

LED Torch by Philipp Frischmuth (444 kB)
Black or white screen
Has Morse code key
Has ads
No strobe light

If I were to pick a winner, it would be LED Torch, for allowing you to black out your screen. If you like discos then iLights would be better.

On another note, the Retina display is amazing. The length of the iPhone 4 display has more pixels than the width of my MBP!

Update 3 Sep 10:
LED Torch now has iAds.
