# River IQ 2 vs Walkers Attack

The clearest difference is rating: Walkers Attack at 4.6 against River IQ 2's 4.2. Walkers Attack also leads on ratings volume (33K vs 6) and update cadence (every 2 weeks vs every 2 months). River IQ 2's advantage is review sentiment (50% vs 25%) and iOS requirement (12.0 vs 14.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. River IQ 2 sells 1 one-off in-app purchase and Walkers Attack sells 19 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Walkers Attack holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Walkers Attack has 33K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of River IQ 2's written reviews are positive against 25% of Walkers Attack's, so the app with the better star average is not the one people write more warmly about.

River IQ 2 ships an update every 2 months, Walkers Attack every 2 weeks. The most recent releases landed on October 10, 2026 and October 21, 2026 respectively.
