# Stroop! vs Lights

The clearest difference is rating: Lights at 4.4 against Stroop!'s 3.9. Lights also leads on ratings volume (130 vs 7). Stroop!'s advantage is in-app purchases (none vs 1) and review sentiment (25% vs 0%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Lights sells 1 one-off in-app purchase. Stroop! asks for nothing beyond the download.

Lights holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Lights has 130 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 25% of Stroop!'s written reviews are positive against 0% of Lights's, so the app with the better star average is not the one people write more warmly about.

Stroop! ships an update every 2 weeks, Lights every 6 weeks. The most recent releases landed on September 29, 2026 and October 10, 2026 respectively.
