Verdict
The clearest difference is update cadence: Gas Checker at every 3 weeks against Keevio2's every 6 months. Gas Checker also leads on rating (5.0 vs 4.6) and device support (3 vs 1). Keevio2's advantage is ratings volume (10 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Gas Checker holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Keevio2 has 10 ratings behind it against 1, so its average is the more settled of the two.
Gas Checker ships an update every 3 weeks, Keevio2 every 6 months. Both last shipped on October 24, 2026.
