Use the GasOkay app to connect to your iGasView gas scale to keep track of your gas usage and get a warning when you are about to run out of gas*. Connect all your iGasView scales using Bluetooth, join them into groups for a quick overview, and you will have complete control of your gas usage.
The GasOkay app from IGT will together with the iGasView (http://www.igt-lpg.com/gasview/) and other smart lpg accessories change the way you think of gas and help you optimize your gas usage.
*you need to be within Bluetooth range and have the app open in order to get current gas levels.
