# Zero4Racer PRO vs Heavy Machines Transporter Sim

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.

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.

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.
