# Grim Bounce vs Boing Ninja

Grim Bounce and Boing Ninja both sit at 4.7 stars, but that hides the real split: 100% of Grim Bounce's written reviews are positive against 56% of Boing Ninja's. Boing Ninja's advantage is ads (none vs shown) and ratings volume (152 vs 3). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Grim Bounce sells 10 one-off in-app purchases and Boing Ninja sells 18 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Grim Bounce against 4.6 for Boing Ninja. That said, the two scores are not equally well evidenced: Boing Ninja has 152 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 100% of Grim Bounce's written reviews are positive against 56% of Boing Ninja's.

Grim Bounce ships an update every 8 days, Boing Ninja every 5 days. The most recent releases landed on October 10, 2026 and October 15, 2026 respectively.
