Editor's review
Download the latest WeatherSignal application, version 3.6, compatible with Windows 10/11 (using emulators such as Bluestacks), Android devices. This free Weather app is developed by OpenSignal.com and is easy to download and install.
Previous versions, including 3.6, are also available. If you need help or have any problems, please let us know.
Description
Features:
✓ 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!

*Thermometer readings are experimental!*
*** 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.
*** PRESSURE ****
Devices that contain barometers include:
Galaxy Nexus
Galaxy S3, S4, Note (1,2,3)
Nexus 4
Nexus 10
Xoom
RAZR MAXX HD
Xiaomi MI-2
Units available:
millibars/hPa inches of mercury aka Hg or inches H
centigrade/celsius and Fahrenheit

Ratings and Reviews
Rating: 4.1/5 based on 7K+ reviews
(*) is required
2 ★ Not ready for prime, worse than Beta status. Excessive resources / battery usage drain. Keeps phone from sleeping at night, slows phone down to a terrible sluggish state Horrible accuracy of temp & all readings. Keep saying its 86* while standing outside in AZ heat of 110*, crowd sourcing makes accuracy worse. Uninstalling, going back toy true / tried AccuWeather app.
4 ★ Still figuring some things out. Accurate abou 99% of the time. Obviously, there are things that can skew the sensors, but if you pay attention, it delivers quite well. Does exactly what I need it to..
5 ★ Great interactive app. Gives more than rain or sunshine. It's radical in some views, which is grand in this case. Horizons building! Give it a chance in your life and others.
2 ★ The temperature reading is always wrong 15 - 20 degrees too low. If you can't get that right what good is it. This application work great on Samsung Galaxy 4 but not on 5. Months ago I sent feedback and was advised to continue using it even though it was bad because they would debugging with that info. Guess they didn't figure it out.
2 ★ Can't wait for my storm tag to link with this app. UPDATE... caused my phone to crash and reboot three times so far. Twice while no other apps where running, only chrome browser and once while the phone wasn't being used (crash notification when I picked it up next). HTC ONE M8... Update. Four times.
4 ★ May be missing something, but doesn't show the weather like normal apps. Just what's happening at time of view. Also what does each coloured balloon mean?
1 ★ The app hasn't been updated since June of 2014 - more than 2 years ago. If you've stopped developing the app, I'd like to know. I try to send reports daily but I'm a little tired of the "welcome messages". How about some new ones? And your algorithms haven't gotten much better over the years. The temperature is always way off.
5 ★ I like this real time weather reporting. Temperatures aren't 100% accurate but it is usually pretty close. Nice to see so many people reporting their current conditions in my area and more places.
1 ★ Tells me it's minus 18 degrees centigrade. If a weather app is inaccurate it's pointless. Il stick to weather timeline which works and looks perfect.
4 ★ Please add dropbox integration. Temp is not accurate but that's probably because of the battery on my phone. But I love the idea of tracking weather for headaches & knee health. Would love to see something for pollen/allergens. Too bad only galaxy 4 senses humidity & acceleration.
3 ★ It use too much battery when ran background...as even completely exit these app but still ran background...need get some works to reduce power hogging...anyway it good nice app...some interestong info...wld give 5 star if developer can reduce these power hogging
5 ★ I love this app. I see this kind of app becoming the cornerstone in weather / environmental monitoring. By using dispersed real time data we can more accurately map our environment and the continual changes of it.
3 ★ Gives current local temp and pressure info offers a trend of the sensors over multiple time bases. I do like it and I like the idea of it, but confess to not really using it. When the sensors jump about its disappointing but you can't really help that.
2 ★ keep improving,don't give up.
4 ★ 1 star for existing. 2 stars for crowd-sourcing. 3 stars for neat tools like light flux and magnetic flux. 4 stars for use-easiness. I am reserving the fifth star for something stellar, but I don't know what it is.
