Tip: App for digital level

[hevansrv7a]

I found two, free apps for iPhone/iPod Touch, and iPad, which give you a digital level that reads to 1/10 degree.

Of the two, I discovered that only this one can be easily and correctly calibrated:

Not bad...the iPhone was within 0.2° and usually within 0.1° when attached to the top my big digital level.

(I think the newer version of A-Level will calibrate now too: http://itunes.apple.com/us/app/a-level/id286059003?mt=8 )

I use the app "clinometer" and have found it very versatile (can't figure out how to post the URL from iTunes). Anyone have an opinion about if the other apps are better? (other than Clinometer being $.99!)
