In case you don't have enough space in your home screen, a clear battery level indicator is available on status bar so that you can see it even when you are browsing the web or sending text messages. It can be configured to show in 3 different colors to reflect high/medium/low battery levels. You can also define your own alerts, so that Battery Widget will automatically notify you about battery status changes.
Battery Widget will not drain your battery, as it does only what it needs to do. When the device is idle, it is not listening to any battery information updates from the system if there are no active alerts

NOTE: For people upgrading, some *permissions* are being listed as new which are not in the app, this is a Android bug, check the permissions in your phone settings to confirm these permissions are absent. See https://code.google.com/p/android/issues/detail?id=63898
NB We never access or read your messages or contacts list. We only need that permission to count your calls and texts to help you keep track of usage.
✓ Signal compass points you in the direction your signal is coming from, just walk towards it!
✓ WiFi map allows you to easily locate nearby public networks.
✓ Coverage maps allow you see the best places for signal.
✓ Speedtest feature allows you to see the true speed of your connection.
✓ NetworkRank allows you to see which carrier is best in your area.
✓ Keep track of your monthly data, text and voice usage so you don’t go over your limit.
✓ See a map of local cell towers.
✓ Help improve our coverage and WiFi maps.

Help contribute to our crowdsourced impartial maps of carrier coverage and wireless hotspots by using our app to improve your connection.
Based on our community-generated data we are able to help keep you better connected by giving you a practical solution to the problems of slow mobile internet and dropped calls. Simply follow our signal compass to walk towards better phone signal or see our in-app coverage maps to work out which carrier is best for where you are, useful if you're thinking about changing. Our wifi maps help you find local public-access wireless networks (WAPs), helpful if you're travelling abroad or just want to find a local cafe with free wifi. Our Stats tab helps you to keep track of your usage, so there’s no danger of you going over your plan limit on data, voice or text. (NB – this is why the app needs permission to access contacts and SMS, these are the permissions needed to count calls and texts, messages are never accessed or read!). Slow mobile internet? Whatsapp or BBM not working? Can't make that crucial skype call? Facebook, Instagram or Twitter too slow to be enjoyable? Run a speedtest to see the real speed of your connection, use the signal booster compass to get a better connection or use our maps to find the nearest free wifi!
Best of all, every time you use the app you're helping to improve it! By helping us to expand our wifi database and improve our coverage maps you're making the app work better and everyone else who uses it.
The best tactic for getting better signal is to follow the signal compass.
Maps not updated in real-time. Don’t worry though, we log the information you share with us to improve our coverage maps and signal information. We’re working hard to make sure the data you contribute to the project is available to everyone as quickly as possible.
- Not all towers and wireless routers are in our database - we’re working on it!
- Verizon & Sprint users will see only one connected tower at a time
- Moving in the direction of your cell tower will not always improve reception due to interference effects/local geography.
- Data is crowd sourced - wireless and antenna locations are calculated by triangulation.
- For GSM, cell tower are identified via cell id and location area code (CID and LAC)
- For CDMA (Verizon, Sprint), cell towers are identified via Network ID, Base sub-station ID and system ID (NID, BSSID and SID).
We map- Coverage and Speed tests for Verizon, Sprint, Vodafone, EE, AT&T, O2, 3, TIM, T-Mobile, Telcel, I WInd, SFR, Wifi and more
Turn your device into a thermometer, barometer, lightmeter and hygrometer - depending on which sensors your device has - with this app your phone is a tricorder & mobile science kit!
By using WeatherSignal you become part of the most ambitious weather crowdsourcing project in the world – helping to record weather patterns on a more localised level than ever before. We are working with numerous meteorological institutions, including the University of Washington, Birmingham University and the UK Met Office. Your readings help us improve weather forecasting for everyone!
Featured in the New Scientist and Scientific American! http://bit.ly/1aFY3Ls
This app is 100% ad-free :)
*Thermometer readings are experimental!*
✓ 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
*** This app is experimental! Readings from sensors may be faulty, we are developing ways of filtering and correcting this. In particular, individual TEMPERATURE readings may be incorrect, but when averaged over many users we get reliable information for our community powered maps. ***
WeatherSignal is designed to help you make use of your phone’s sensors. What the app shows depends on what model of phone you have and how many sensors it has. The app works best on the Galaxy S4 (as that phone has the most sensors) but has functionality on most Android devices
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)
You can see graphs and maps of all these values live or over time.
This app is also one of the first to feature Google's Activity Recognition: monitor when you're walking, in vehicle, on a bicycle. You can save the results to CSV and perform your own analysis/create maps, for example for quantified self tracking
*** NOTE ON TEMPERATURE READINGS ***
We’ve come up with an algorithm that translates battery temperature into ambient temperature – making your phone a thermometer. For each user this can sometimes be a bit approximate but we've discovered that 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 (perhaps because it's been in your pocket or has been charging or intensively used) then the readings will be higher than air temperature.
*** PRESSURE ****
Devices that contain barometers include:
Galaxy S3, S4, Note (1,2,3)
RAZR MAXX HD
millibars/hPa inches of mercury aka "Hg or inches H
centigrade/celsius and Fahrenheit
You might also be searching for: luxmeter, lightmeter, light meter, magnetometer, barometer, hygrometer, accelerometer, thermometer ... if your phone has it, WeatherSignal reads it, graphs it, maps it, saves it.
