# Fastrack Smart World vs Reflex Active Red

The clearest difference is rating: Fastrack Smart World at 4.5 against Reflex Active Red's 3.6. Fastrack Smart World also leads on update cadence (every 10 days vs every 3 months) and ratings volume (1K vs 10). Reflex Active Red's advantage is review sentiment (37% vs 22%) and iOS requirement (12 vs 16). 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.

Fastrack Smart World holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Fastrack Smart World has 1K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 22% of Fastrack Smart World's written reviews are positive against 37% of Reflex Active Red's, so the app with the better star average is not the one people write more warmly about.

Fastrack Smart World ships an update every 10 days, Reflex Active Red every 3 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
