In the age of wildly fluctuating (and ever-increasing) gas prices, this gas-price-finding app is invaluable. It predicts the gas prices for the following day as well (posted every weekday around 5 pm ET). The cities supported so far include are Calgary, Edmonton, Kamloops, Kelowna, Vancouver, Winnipeg, Montreal, Saskatoon, and all major Ontario metropolitan areas. Unfortunately, the app doesn’t cover the East Coast at this time.
