Verdict
The clearest difference is price: Installer Connect at Free against Gas Rate Calculator's $4.99. Installer Connect also leads on update cadence (every 3 months vs every 12 months). Gas Rate Calculator's advantage is review sentiment (77% vs 36%) and iOS requirement (7.0 vs 17.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
