Twinkler Software has just released a new BlackBerry application that will prove to be very useful if you’re constantly on the move and are a heavy WiFi user (like me).

WiFi Hero is an application that, once installed, controls when WiFi connections are on/off allowing you to conserve battery life based on where you are or what your BlackBerry is doing. Here’s how it works:

• Location Based. In this mode, WiFi Hero will automatically learn the location of the WiFi Hotspot you are currently connected to, and when WiFi is not connected (you are out of range of this Hotspot), WiFi Hero will automatically turn off WiFi – and when you come back to the same Hotspot location, it will automatically turn on WiFi.
• Screen Status. In this mode, WiFi Hero will automatically turn on WiFi when the screen is on and automatically turn off WiFi when the screen is off – making this very useful when you use your Blackberry to browse the web.
• Charging Status. In this mode, WiFi Hero will automatically turn on WiFi when the device is on charge, and automatically turn off WiFi when device is not charging and on battery power.
• This application is very small (about 12K) and is optimized for battery life.

WiFi Hero will work on all WiFi-enabled BlackBerry devices running OS 4.5 and higher and is available in the store for $4.99 with a free trial available.
