Zero4Racer Pro is back. The original tilt-and-clutch drag racer returns, rebuilt for modern iOS. Same on-screen clutch button, same accelerometer throttle, same 400-metre rush from the line to the finish. Race - Tilt to feed throttle, hold the clutch button to slip the drivetrain, tap the shift lever at the right RPM and run the 400 m. - Two accelerometer-handling modes (Horizon and Vertical) for the way you actually hold the phone. - Calibrate your neutral tilt once in Options and forget about it. Choose your driver - Create your profile: pick a driver character, pick a name, race. - Free characters are always available; extra characters come with the optional Premium one-time purchase. Garage - Buy cars from a small starter catalogue, install and renew parts. - Watch the car's run count and per-part wear tick up after each race. Race against your own ghost - Pick "Best-time ghost" before a race and a marker of your fastest prior lap in the same class slides along the track next to you. - Local-first. No custom server, no uploaded replays. Sound - Tunable engine sample with pitch and gain tied to live RPM. - Gear-change and finish SFX. Volumes for engine / SFX / BGM live in Options. - Background music from your own library plays through; the app does not interrupt it. Scores - Best-time-per-class summary plus a filterable top-20 board. - Sort by best time or by latest finish. - Records persist locally and remain available offline. - Optional Apple Game Center ranking starts with the Class A / 400 m best-time board. Game Center is Apple-hosted; Zero4Racer does not run a custom leaderboard backend. PREMIUM CHARACTERS (optional) Premium Characters is a one-time in-app purchase. Buy it once and every driver character is unlocked. You pay a single time; there is no recurring charge. The purchase can be restored on the same Apple Account, including after a reinstall. All core racing gameplay is free — the purchase only unlocks additional driver characters. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.jtechs.com/privacy-policy/index.html No ads. No tracking. Local scores always work.

Verdict
The clearest difference is review sentiment: Space Agency at 75% against Zero4Racer PRO's 29%. Space Agency also leads on rating (4.4 vs 3.1) and ratings volume (738 vs 35). Zero4Racer PRO's advantage is price (Free vs $1.99) and update cadence (every 2 weeks vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
