# Stack AR vs Whack!

The clearest difference is review sentiment: Whack! at 100% against Stack AR's 32%. Whack! also leads on update cadence (every 4 days vs every 4 months). Stack AR's advantage is rating (3.8 vs 3.0) and ratings volume (2.1K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stack AR sells 1 one-off in-app purchase and Whack! sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Stack AR holds the better App Store score, 3.8 against 3.0. That said, the two scores are not equally well evidenced: Stack AR has 2.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 32% of Stack AR's written reviews are positive against 100% of Whack!'s, so the app with the better star average is not the one people write more warmly about.

Stack AR ships an update every 4 months, Whack! every 4 days. The most recent releases landed on November 10, 2026 and October 31, 2026 respectively.
