WeatherSignal uses native phone sensors to measure local atmospheric conditions, which are then displayed on our live-updating weather map.
Join the world's largest crowdsourced weather project.
✓ Readout for all the sensors on your device (think Tricorder - but real!)
✓ Widgets for temperature, magnetic, light, humidity and pressure sensors (if you have them)
✓ Save all data to CSV - play with it however you like
✓ Map of readings of other users and of your own, see averages within each map window, click on icons to see full readout
✓ Manual reports
✓ Tons of graphs (for geeks like us :))
✓ Contribute to our maps (you can turn off sharing in settings)
✓ Share data to help us improve the weather forecast
✓ Looks great on tablets
Turn your device into a thermometer, barometer, lightmeter and hygrometer - depending on which sensors your device has - with this app your phone is a mobile science kit!
By using WeatherSignal you become part of the world's most ambitious weather crowdsourcing project – helping to record weather patterns on a more localised level than ever before. We are working with numerous meteorological institutions, including the Univ. of Washington, Birmingham Univ. and the UK Met Office. Your readings help us improve weather forecasting for everyone!
*** This app is experimental! Individual TEMPERATURE readings may be incorrect, but when averaged over many users we get reliable information for our community powered maps. ***
The app works best on the Galaxy S4 since it has the most sensors. Get a StormTag to add sensors to your phone.
The WeatherSignal app can measure: ✓ Pressure (certain devices only) ✓ Temperature (see note) ✓ Light Intensity ✓ Humidity (Galaxy S4 only) ✓ Magnetic Flux ✓ Acceleration (turn on in application settings)
This app features Google's Activity Recognition: monitor when you're walking, in vehicle, on a bicycle. Save the results to CSV and perform your own analysis/create maps, for example for quantified self.
*** TEMPERATURE ***
We’ve come up with an algorithm that translates battery temperature into ambient temperature – making your phone a thermometer. For each user this is approximate but there is a very strong correlation between battery and ambient temperature when spread over a crowd of users. If you are using a cell phone without an external thermometer then the temperature reading you’ll see is a battery temperature reading converted through our algorithm. Often the algorithm will get it wrong, but we've shown that with appropriate averaging and filtering, these readings correlate extremely well with external ambient air temperature.
The Galaxy S4, which has an ambient air temperature thermometer, may produce incorrect readings if the phone is hot due to use.
Units available: millibars/hPa inches of mercury aka Hg or inches H centigrade/celsius and Fahrenheit

UPDATED ON: Jun 17, 2014
INSTALLATIONS: 100,000 - 500,000
LATEST VERSION: 3.6
REQUIRED ANDROID VERSION: 2.2 and up
read phone state and identity
Allows the application to access the phone features of the device. An application with this permission can determine the phone number and serial number of this phone, whether a call is active, the number that call is connected to, ect.
approximate (network-based) location
Access location sources such as the cellular network database to determine an approximate phone location, where available. Malicious applications can use this to determine approximately where you are.
precise (GPS) location
Access precise location sources such as the Global Positioning System on the phone, where available. Malicious applications can use this to determine where you are, and may consume additional battery power.
full Internet access
Allows an application to create network sockets.
view network state
Allows an application to view the state of all networks.
view Wi-Fi status
Allows an application to view the information about the state of Wi-Fi.
automatically start at boot
Allows an application to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the application to slow down overall performance of the phone by constantly running.
change Wi-Fi state
Allows an application to connect to and disconnect from Wi-Fi access points, and to make changes to configured Wi-Fi networks.
modify global system settings
Allows an application to modify the systemʼs settings data. Malicious applications can corrupt your systemʼs configuration.
modify/delete SD card contents
Allows an application to write to the SD card.
control vibration alert
Allows the application to control the vibration alert.
