# Optix vs Sardines Carpool

The clearest difference is review sentiment: Sardines Carpool at 100% against Optix's 67%. Sardines Carpool also leads on update cadence (every 4 days vs every 5 weeks). Optix's advantage is rating (4.9 vs 4.7) and ratings volume (149 vs 12). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Optix holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Optix has 149 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 67% of Optix's written reviews are positive against 100% of Sardines Carpool's, so the app with the better star average is not the one people write more warmly about.

Optix ships an update every 5 weeks, Sardines Carpool every 4 days. The most recent releases landed on September 24, 2026 and June 5, 2026 respectively.
