Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Hey there — the GenFuel team is back with fixes that make the numbers you rely on even more trustworthy. We tuned the price suggestion chips and the +/- stepper for currencies with smaller unit prices (like USD, EUR, and GBP) — they now offer real, useful options instead of collapsing into a single choice. We also corrected the default USD fuel price estimate, and gave the app a fresh new launch screen with our own logo. Thanks for keeping GenFuel in your generator toolkit — we're already working on what's next!
