Try branded smartphones for best results.
Advanced features include multiple reference dates, a database of Isotopes with their half life constants and a log file to easily record activities.
(The paid version has facilities to save the log file and edit the isotope database. It also doesn’t have the ad banner.)
Simply long-press the reference buttons to enter reference dates then enter an activity and use Ref1, Ref2 to show the activity decayed to that reference. Use the clock button to show the activity decayed to the current time.
The internet and network status permissions are for the ad banner and are not present in the paid application.

Curious about what sensors are inside of your phone? How accurate are they? Who are they made by? Is the data that your handset manufacturer provided correct? Then check this app out!
At times hardware manufacturers are known to subtly change the internal sensors of a handset without updating technical documents - and at times this has been known to affect rooting attempts with third part drivers.
Using this app you can get a list of all the sensors present in your device and also access their specifications.
Max, Min and Avg function is installed!

* This software includes some source codes distributed on the Apache
It uses a Fast Fourier Transform algorithm to implement high precision A, B, C and Z weighting filters and sophisticated digital signal processing techniques to achieve the best possible SPL readings out of your Android phone or tablet.
It displays the current, maximum and minimum values in decibels, and generates 3 kinds of sound pressure level versus time charts. The display can be turned upside down to allow pointing the mic at the sound source.
### Please calibrate before the first use! ###
- true A, B, C and Z Weighting (ANSI S1.4)
- numeric dB, dBmin and dBmax display
- simple calibration interface
- Automatic Calibration function (no professional SPL meter required for reasonable startup accuracy)
- sliding sound level versus time chart
- sliding max, min and average soud level versus time chart
- accumulated sound level exposition chart (dosimeter)
- saves chart screenshots to the SD card
- dominant frequency display
- 22Khz bandwidth at the input of the weighting filter
- 1024 point real time FFT and digital sound processing
This is a real working radioactivity counter. You only need a BLACK TAPE to cover the lenses !!
Disclaimer: The type of radiation picked up by the camera can be dangerous/detrimental to the user's health as well as cause damage to the device.
Its NOT a JOKE! The App is using the camera sensor to detect radiation, like a geiger mueller counter, of course with a smaller area. We tested several mobile phones at the Helmholtz research facility in Munich, using a professional radiation device in the range of 2-10 µGy/h till 1-10 Gy/h (CS137 and CO60). The CMOS sensors can detect primary gamma radiation and some higher beta radiation (depends on the shieldings in the mobile phone). Typically not going into saturation as most GM tubes. See FAQ on our homepage for what you can measure and how.
PLEASE SEND US FEEDBACK via EMAIL !! We add new devices in short intervals.
Attention: the tape must shield the light completely. Please check with a light source !
On our homepage you find several measurement result for different devices we tested so far. Some are excellent, some not that sensitive.
Feel free to use our table to assign radiation values to our counter measurements when you have the same device.
The real values might differ as sensors can change. There we need your help and the help of the manufactures for a future calibration service.
You can use the contact button in the help menu to provide us with feedback and please use it.
If you need any help, PLEASE send us an email. We have cannot answer the comment section below, so please ask us first on measurment problems. We help as fast as possible. Please contact us on any problems you have with this application! Look at our videos, more are comming soon. Attention: The counts per minute (CPM) for the background noise should be low (increase the noise setting if not). This is camera noise not radiation noise basically. If the radiation increases then also counts from the radiation adds to the CPM values (see our tables for the sensitivity). If you have a phone with 200 CPM for 100 uGy/h then the background noise produces for 100 nGy/h only 0.1 CPM. That means in 10 minutes ONE counts in 100 minute TEN counts adding to the CPM0 (noise of sensor). So you need a LONG time to measure for low radiation values on this device. Attention: AM241 (smoke detectors) only emit ALPHA rays, they get stuck in the plastic of the phones. H3 (tritium - watches etc) are beta emitters with 45 keV. They also get stuck quickly, mainly already in the watches. K40 (KCL for example contains 16 Bq/g) are beta emitters with small amount of gamma (due to positron collisions)- you need also a long integration time to measure them. Same for TH rods (2% Thorium) mainly alpha rays, then beta and some gamma. Very small diameter ! You need a large area to detect them (best GM with mica windows). The CMOS sensor of the camera only has 2mmx2mm.
Good objects are TH lenses (up to 30% TH232), pitchblend (gamma of decay products) and CS137 for checking food which might be contaminated (if larger 1 uSv/h). Don't experiment with radiation sources !!!

* unit converter (Sievert, Gray, Rem...)
We just released a comprehensive help on our homepage --
Important you NOISE value should be similar as in our tables, if it is too high check the tape to cover the lense - use multiple tapes if necessary and start calibration again !!! Please before writting a bad one star comment write us we will help you very quickly PLEASE !!!

instruction and help:
The input from the hardware key is possible in the Android version. Can it be a setting, the key arrangement be a numeric keys type or the telephone type be selected.
Because the operation results in a real machine are little, it is free in the beta version still. GALAXY S II is a confirmed operation. The action reporting in various models from everybody is waited for. Moreover, please report by all means when you come by there is a test environment in bluetooth numeric keypad.
NOTE: There are no functions available in this software without a connection to a PED+ dosimeter.

Atom Tag contains a radiation sensor (Geiger tube), all electronics needed to power and get readings from Geiger tube, Bluetooth 4.0 interface and lithium-ion battery. Tiny plastic housing protects Geiger tube and electronics. Smartphone or tablet PC is used to process information gathered from radiation sensor and show readings on screen. Application for run with Atom Tag can be downloaded using AppStore (for iOS) or Google Play (for Android). Atom Tag don't contain hazardous or radioactive substances, use of Atom Tag is safe for people, animals and environment.
Atom Tag works in standalone mode if wireless communication with smartphone or tablet PC is lost. 3 user-programmable dose rate and accumulated dose thresholds with different alarm signals (sound or vibration) can be programmed by user for standalone mode. Information on accumulated dose is stored while Atom Tag is in standalone mode and can be read after establishing wireless communication. One smartphone or tablet PC can be connected to many Atom Tags at once.
Charging of built-in lithium-ion battery should be performed using original charging cable and any computer or smartphone charger with USB port.
