# ForzaTune vs SIM

The clearest difference is review sentiment: ForzaTune at 84% against SIM's 43%. ForzaTune also leads on in-app purchases (none vs 24). SIM's advantage is update cadence (every 2 weeks vs every 2 months) and rating (4.6 vs 4.3). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. SIM sells 24 one-off in-app purchases. ForzaTune asks for nothing beyond the download.

SIM holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 149 and 445 respectively. Written reviews complicate that: 84% of ForzaTune's written reviews are positive against 43% of SIM's, so the app with the better star average is not the one people write more warmly about.

ForzaTune ships an update every 2 months, SIM every 2 weeks. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
