Contraptor is a physics playground where you build machines to solve hand-crafted puzzles. Drop in rods, wheels, pins, motors, and welds, wire up a contraption, hit Play, and let real physics decide how it works. NEW TO BUILDING? START WITH PLAY. Thirty short levels teach the whole game one trick at a time. Your first level hands you a single oval. Thirty levels later you're wiring motors, bracing with ghost rods, and threading payloads through wormholes. Every level keeps the machine you built to beat it, so you can come back and watch it run. Beat them all and you earn a Certificate of Completion with your name on it. THEN TAKE ON THE COMMUNITY. Every challenge is a puzzle: get the payload (or many payloads) to the target(s) using whatever that challenge allows. Some let you shove pieces around, some ration your parts with Twists, some bend the rules with wormholes and moving hazards. Solve it and you've earned bragging rights. Then flip it around: design your own challenge, prove it's solvable if you like, and dare everyone to crack it. • Build with real 2D physics — mass, gravity, momentum, friction, bounce, damping, and motors • 30 hand-built levels that teach every tool, plus a certificate at the top • A growing library of community challenges, with search • Design your own, prove they're solvable, and post them • Twists: cap the parts, cap the speed, or hand solvers exactly the toolbox you choose • Wormholes, slow-motion zones, and other rule-benders • Rate, follow other builders, and climb the leaderboards • Hands-on tutorials for every tool • Universal — iPhone and iPad Seeing a solution isn't the same as building one. That skill gap is the whole game. Contraptor uses your iCloud account for community features (posting, rating, following, leaderboards, usernames). You can play every level, follow the tutorials, and browse and play everything in the Community without iCloud — it's only needed to post or interact. iCloud is free.

Verdict

The call

The clearest difference is ads: Contraptor at none against Earth Editor's shown. Contraptor also leads on update cadence (every 3 days vs every 4 months) and review sentiment (100% vs 79%). Earth Editor's advantage is ratings volume (919 vs 4) and rating (4.3 vs 4.0). On price, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Earth Editor holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Earth Editor has 919 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 79% of Earth Editor'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.

UpkeepUpdate frequency

Earth Editor ships an update every 4 months, Contraptor every 3 days. The most recent releases landed on October 16, 2026 and October 5, 2026 respectively.
