Measure the Night Dky – Dark Sky Meter Review

Dark Sky Meter is the first app for iPhone to allow users to accurately measure the brightness of the night sky. Amateur astronomers and dark sky advocates are likely familiar with the Sky Quality Meter (SQM) device. This app gives you an SQM in your phone and for the 4S and 5 gives very accurate results without having to buy an SQM. The app is well worth the purchase price.
