SmartWiFi is a BlackBerry app that’s designed to help prolong your battery life by turning off your WiFi when you’re not using it.
Here’s how it does that. You set up one or more preferred WiFi hotspot locations, and once you wander out of the zone, SmartWiFi shuts off the WiFi on your mobile device. It determines your location by tracking your movements from cellular towers. When you come back to your preferred spot, the app will turn your WiFi back on.
For instance, you can set up your home and work wireless networks as preferred spots. When you leave the the house, your WiFi will shut down, helping you squeeze a little extra battery life out of your phone. When you get to work, it turns back on.
SmartWiFi supports up to 100 preferred locations. The app normally costs $4.99, but you can download it for free today only as part of Handango’s Free App Friday promotion.
