How to track gas-price trends on iPhone
Before you fill up, get some context: what has the average price been doing, and how does this week compare with the past few months?
GasPulse is a free iPhone app for following weekly U.S. gasoline-price averages, historical trends, and a simple outlook. It helps you understand your state or region’s price movement. It does not find the cheapest nearby station or promise a lower price tomorrow.
A quick check before your next drive
- Choose the area you want to follow. Use the state selector. Check whether the value represents that state or its applicable region; some states share a regional data series.
- Read the reporting date. The latest weekly average is an observation for a particular week. It is not a live quote from a gas station. A number without its date is easy to misread.
- Choose a history range. GasPulse offers 1M, 3M, 6M, 1Y, and 5Y. A short view helps you see recent movement; a longer view gives that movement context. Keep the same range when comparing areas.
- Separate history from the outlook. The chart describes past movement. The outlook is an estimate of what may happen next. A price can have fallen over your selected history range while the outlook points upward.
- Check the station’s posted price. Use the app for market context and the station’s price for the actual purchase. GasPulse does not provide station locations or individual pump prices.
What a trend can—and cannot—tell you
A weekly average helps answer “Are prices moving up or down in this area?” It cannot tell you whether one specific station will change its price today. The EIA describes retail gasoline prices as a combination of crude oil, refining, distribution and marketing, and taxes. Those influences provide context, not a personal fill-up guarantee.
