# Metal Force vs Bumper.io

Metal Force and Bumper.io both sit at 4.5 stars, but that hides the real split: 79% of Metal Force's written reviews are positive against 38% of Bumper.io's. Metal Force also leads on ads (none vs shown) and iOS requirement (9.0 vs 14.0). Bumper.io's advantage is ratings volume (196K vs 35) and update cadence (every 3 weeks vs every 2 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Metal Force sells 5 one-off in-app purchases and Bumper.io sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Metal Force against 4.6 for Bumper.io. That said, the two scores are not equally well evidenced: Bumper.io has 196K ratings behind it against 35, so its average is the more settled of the two. Written reviews are what separate them: 79% of Metal Force's written reviews are positive against 38% of Bumper.io's.

Metal Force ships an update every 2 months, Bumper.io every 3 weeks. The most recent releases landed on November 1, 2026 and November 4, 2026 respectively.
