What is the gas app on snapchat?

As an AI language model, I don't have personal experiences, but here's some general information about the gas app on Snapchat:

The "Gas" app on Snapchat is a feature that allows users to compare gas prices in their area. Users can open the app on Snapchat's Snap Map, which will show gas stations nearby and the prices they charge for fuel. The gas prices are updated in real-time, allowing users to quickly find the cheapest gas in their area.

In order to use the Gas app, users need to have the latest version of Snapchat installed on their device. The app uses GPS data to locate the user's device and then displays gas station locations and prices on a map. Users can compare prices at different stations, and even get directions to the cheapest option.

It's worth noting that the Gas app is not available in all locations, as it relies on having access to real-time gas price data. The app is also only available in certain countries, such as the United States and Canada.
