!-Warning- This app is designed for a very specific task-! This app is of no use whatsoever without a corresponding bluetooth enabled device designed to accept the correct serial commands. So unless you know what to use this app for, don't bother downloading it. See my website for details.
This app can be used with a bluetooth enabled Geiger–Müller counter, via a simple serial protocol. The required commands are detailed on my website. This app will show the counts per minute, by first averaging the last samples and multiplying them up. The same weight is placed on all samples. Also shown is a Siverts per hour indicator, or dose rate, and a historical graph. It is up to the Geiger–Müller counter to send the correct conversion rate.
