Rev 2.2. New algorithm for more stable camera cold starts, needs less recalibration, bugfix on unkown devices, and experimental upload function for statistics., new devices supported up to iPhone 6 - attention some feature made it incompatible to older devices or not having a sim card -- we work on this for the next version -- stay on the old version 1x when affected.

Great app but needs the radiation click sound.

Awesome information

I just had radiation treatment for my thyroid and it has been helpful to know how much radiation remains in my neck and watch it as it dissipates. It provides warning quite well when the phone is near my neck.

Amazing sensor usage; not fake

Hats off to the developer for implementing a real measurement tool for radioactivity. Visit his website to see his calibration data, I know that measurements from my iPhone 6p matched my 'real' instrument by detecting faint radiation from my granite countertops.
