# Fuel vs Tuning

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Fuel holds the better App Store score, 3.1 against 2.4. Both are backed by a comparable volume of ratings — 33 and 29 respectively. Written reviews point the same way: 50% of Fuel's written reviews are positive against 21% of Tuning's.

Fuel ships an update every 10 months, Tuning every 2 months. Both last shipped on October 15, 2026.
