# Left vs Fluid Friction

The clearest difference is rating: Left at 4.6 against Fluid Friction's 4.1. Left also leads on ratings volume (461 vs 7) and update cadence (every 3 days vs every 10 days). Fluid Friction's advantage is monetization model (freemium vs paid) and iOS requirement (17.0 vs 26.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Left sells 28 in-app purchases, starting at $0.99 per 7 days and Fluid Friction sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Left holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Left has 461 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 73% of Left's written reviews are positive against 75% of Fluid Friction's, so the app with the better star average is not the one people write more warmly about.

Left ships an update every 3 days, Fluid Friction every 10 days. Both last shipped on October 25, 2026.
