# Project Peon vs RobotMania

The clearest difference is ratings volume: RobotMania at 768 against Project Peon's 8. RobotMania also leads on update cadence (every 3 days vs every 2 weeks). Project Peon's advantage is review sentiment (100% vs 84%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Project Peon sells 2 one-off in-app purchases and RobotMania sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

RobotMania holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: RobotMania has 768 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 100% of Project Peon's written reviews are positive against 84% of RobotMania's, so the app with the better star average is not the one people write more warmly about.

Project Peon ships an update every 2 weeks, RobotMania every 3 days. The most recent releases landed on October 29, 2026 and November 3, 2026 respectively.
