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. Just the drag race. Universal landscape on iPhone, optimised for the modern screen sizes while honouring the original game's feel. (c) 2026 J-Tech Creations
