# Flippy Knife vs Stack Rush

The clearest difference is rating: Flippy Knife at 4.6 against Stack Rush's 3.7. Flippy Knife also leads on review sentiment (73% vs 33%) and ratings volume (36K vs 3). Stack Rush's advantage is update cadence (fortnightly vs every 5 weeks) and iOS requirement (12.0 vs 15.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flippy Knife sells 10 in-app purchases, starting at $3.99 per 7 days and Stack Rush sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Flippy Knife holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Flippy Knife has 36K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 73% of Flippy Knife's written reviews are positive against 33% of Stack Rush's.

Flippy Knife ships an update every 5 weeks, Stack Rush fortnightly. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
