It is not really a forecasting service and it won't tell whether you will need an umbrella tomorrow when you leave home. What WeatherSignal does is to use the device's sensors to display information about the current conditions. Top end Android phones like the Samsung Galaxy S4 and others have a lot of built in sensors to measure temperature, pressure, humidity and even light and magnetic flux.You can see all the readings in the left-hand screen shot.
Tap any of the readings to switch to a live display, shown on the right for temperature. It shows the minimum, maximum and average, plus a chart for whatever time period you choose - 10 minutes, an hour, 12 hours, a day, week or month. There is a live display that shows live figures and a live sideways scrolling chart too.
Your phone is just like a tricorder from Star Trek! You can move it around and see how the magnetic flux density or light levels vary.
Swiping sideways reveals a map and other users with the app are displayed with pins. You can tap a pin to see what their readings were and when they were recorded. It's anonymous, so you don't know the user and you just see the readings like those shown above.
It is interesting to see charts showing how readings change over a week or month, or to quickly check what the current temperature is. Falling pressure is an indication of rain and other bad weather, whereas rising pressure means fine, clear weather, so you can make your own weather predictions of sorts.
WeatherSignal is interesting and it is free. Search for it in the Google Play Store.
