Comments on Radioactivity Counter for Android

This app is great it really works I've tested it against a Geiger Counter the readings were accurate to love it!!!

Works on my phone. Detected coal ash radiation. Works on my phone. Detected coal ash radiation using black electrical tape as covering.

I have a galaxy s3 the app seems to work rather well, I wish there was an inbuilt scale that can be brought up when requested that could show what a safe dose is compared to the readings that you have got. In terms of safety this is a good idea because if you have a known comparison of what is safe to compare to your own readings, it may stop someone from being exposed to not safe levels. As it is, I have seen 40-60 cpm and have no idea if this is normal, or not normal background radiation, I wish there was something in the app I could compare the results too so I would have a better idea of the strength of source material. (40-60 cpm were found on a rainwater runoff leading to a drain), with Fukushima now becoming a problem in the Northern Hemisphere, a comparison chart of safe and unsafe levels is a must on the phone. *****ATTENTION***** I have discovered there is governmental interference on this app, they are adjusting the sensitivities and denying you a full truthful count, will you please use your own scientific results to create a bombproof version that cannot be adjusted, and gives results based on research for each device. This is too important to let go of, thank you.
★★☆☆☆
Didn't work on Nexus 4, no reply to emails I bought the $4+ app, and installed it to a Nexus 4 with the back lens cover covered with 2 pieces of black electrical tape. I borrowed a real Geiger counter and some radioactive samples that read about 10-20x above background when very close to the sensor. One was tested even though a thin metal lid with both this app (and nexus 4) as well as the real Geiger counter. After following the instructions and allowing the app to calibrate, it settled on a background count around 20 (I tried it several times, and it was roughly 20 each time). The app does mention something about a 60-minute test but no amount of searching would allow me to figure out how to change that time. After calibrating (~20), tried detecting the samples. What would normally take the Geiger counter from ~20 cpm to ~500 cpm took this app from 20 up to 26. It is barely statistically significant. Reviewed the website, noting I should have had more than enough sensitivity to detect this. After failing to get useful results, I sent 2 emails to the developer from their site. Their site asks you to email them before you give them a one-star rating. After no reply in 2+ wks. (still nothing) I rated.
