ISampler Lite is a random sampling Application. It provides a random reminder to sample the population you are measuring. It also provides a quick and easy way to record your observations.How it works: The iPhone beeps randomly during the sample period (Default meantime - 90 minutes) . When the phone beeps the wearer unlocks the phone and taps an activity or condition that was happening at the time of the beep. The current activities are based on standard built-in templates. A standard report format is included.
