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 call

The clearest difference is rating: Heavy Machines Transporter Sim at 4.2 against Zero4Racer PRO's 3.1. Heavy Machines Transporter Sim also leads on iOS requirement (13.0 vs 15.0). Zero4Racer PRO's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 4 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zero4Racer PRO sells 2 one-off in-app purchases and Heavy Machines Transporter Sim sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Heavy Machines Transporter Sim holds the better App Store score, 4.2 against 3.1. Both are backed by a comparable volume of ratings — 35 and 21 respectively. Written reviews complicate that: 29% of Zero4Racer PRO's written reviews are positive against 14% of Heavy Machines Transporter Sim's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Zero4Racer PRO ships an update every 2 weeks, Heavy Machines Transporter Sim every 4 months. The most recent releases landed on October 26, 2026 and October 21, 2026 respectively.
