Grilling season has official begun. Make it more enjoyable with GasWatch. This app connects to a Bluetooth scale for your your propane tank, and measures the tank’s weight to give you an accurate readout of how much gas you have left. It can also alert you when you’re running low, and tell you how much cooking time you have left — so you don’t put on a roast that takes an hour and a half to cook when you only have 45 minutes of gas remaining.
