Features

When you are not near a WIFI network, your phone's radios are continuously scanning for a WIFI signal where there may be none. Similarly, if you are within range of a WIFI network, it is much more battery efficient to use WIFI than your phone's 3g/4g radios, as well as saving data. WhyFi provides a range of features to help solve this problem.

• Clean, minimalist User Interface: See exactly what the app is doing at any time.
• Complex timing mechanism that intelligently toggles your WIFI radios on and off when WIFI access points come into and out of range.
  
• Automatically disable WIFI if your device has been inactive for an extended period of time. On tablets, this can extend battery life by days!
• Automatic Bluetooth disabling! On some devices, Bluetooth can use a large amount of energy. This feature will disable Bluetooth when it is no longer in use, helping to save that precious battery power.
• Fully customizable settings: Alter any of the different timings that WhyFi uses to help save you battery life.
