# Power Inc vs Contraptor

The clearest difference is rating: Power Inc at 4.6 against Contraptor's 4.0. Power Inc also leads on ratings volume (547 vs 4) and iOS requirement (15.0 vs 18.0). Contraptor's advantage is in-app purchases (none vs 13) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Power Inc sells 13 one-off in-app purchases. Contraptor asks for nothing beyond the download.

Power Inc holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Power Inc has 547 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 68% of Power Inc's written reviews are positive against 100% of Contraptor's, so the app with the better star average is not the one people write more warmly about.

Power Inc ships an update every 6 days, Contraptor every 5 days. The most recent releases landed on October 27, 2026 and October 22, 2026 respectively.
