Verdict
The clearest difference is rating: Fuel at 3.1 against Tuning's 2.4. Fuel also leads on review sentiment (50% vs 21%) and iOS requirement (13.4 vs 15.0). Tuning's advantage is update cadence (every 2 months vs every 10 months). On price, ratings volume, ads and in-app purchases there is nothing between them.
