Rusty Gas Prices
Gas Price Monitoring & Pattern Analysis System
rustgraphqlreqwestserdetokiodata analysis
I was speaking with a friend about having some kind of app to monitor gas prices throughout the year, but moreso throughout shorter time periods, study their patterns in hopes of analyzing gas prices across locations. And I took matters into my own hands to get my friends their optimal gas stations after reading a reddit thread of how someone programmed their home assistant to monitor gas prices.
