# Flippy Knife vs Rumble Bag

Flippy Knife and Rumble Bag both sit at 4.6 stars, but that hides the real split: 73% of Flippy Knife's written reviews are positive against 37% of Rumble Bag's. Flippy Knife also leads on ratings volume (36K vs 4.5K). Rumble Bag's advantage is update cadence (every 8 days vs every 5 weeks). On price, rating, ads and in-app purchases 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 Rumble Bag sells 10 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Rumble Bag holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Flippy Knife has 36K ratings behind it against 4.5K, so its average is the more settled of the two. Written reviews complicate that: 73% of Flippy Knife's written reviews are positive against 37% of Rumble Bag's, so the app with the better star average is not the one people write more warmly about.

Flippy Knife ships an update every 5 weeks, Rumble Bag every 8 days. The most recent releases landed on November 5, 2026 and November 4, 2026 respectively.
