There are a lot of other flashlight apps in the Google Play Store.. My personal favorite app with flashlight is called Swiss Army Knife, it has a lot of other tools also.
It's okay.... I like the HTC Flashlight better. It's just the light, with multiple levels at a tap. The levels are on the phone already. I don't need a ruler. Compass is fun though.
I lost mine, too. Hub is no longer supported by HTC and has less than half of what it did when I first bought the phone. Quickshortcutmaker used to be an alternate source, but it doesn't seem to be able to find it either.
