So you are tired of having to guess how much propane is left in the tank? The Smart GasWatch is a smart propane tank scale with a gas level indicator that takes the guesswork out of the process and measures how much propane is left in the tank. It pairs with your smartphone via Bluetooth to let you know what you can do with the amount of gas left.
The companion app for the Smart GasWatch runs on iOS/Android devices. To get started, just set your tank onto the GasWatch Ring, turn the device one and connect it to your phone, and you are set. The Smart GasWatch provides you with low level alerts. You can find out more on Indiegogo.
