About Toggle EQ
The equalizer from Smart Android Apps is very good, but to turn it on and off without opening the full application there is only a 1x4 widget or two 1x1 widgets (one turns on, one turns off). This app allows the equalizer to be toggled on and off with a single 1x1 app on your launcher screen. The app detects the status of the equalizer, so it does not matter if you turn it on and off in other ways, you only need to touch this app once to toggle the on/off status of the equalizer.
I have nothing to do with Smart Android Apps.
