# Nitro RC vs Slot Car HTR+

The clearest difference is update cadence: Nitro RC at every 4 months against Slot Car HTR+'s every 50 months. Slot Car HTR+'s advantage is rating (4.2 vs 3.9). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Nitro RC sells 1 one-off in-app purchase and Slot Car HTR+ sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Slot Car HTR+ holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 56 and 27 respectively. Written reviews complicate that: 64% of Nitro RC's written reviews are positive against 59% of Slot Car HTR+'s, so the app with the better star average is not the one people write more warmly about.

Nitro RC ships an update every 4 months, Slot Car HTR+ every 50 months. Both last shipped on October 23, 2026.
