# Car Mechanic vs Material Engineering

The clearest difference is rating: Material Engineering at 5.0 against Car Mechanic's 3.6. Material Engineering also leads on ads (none vs shown). Car Mechanic's advantage is ratings volume (27 vs 2) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Car Mechanic sells 1 one-off in-app purchase and Material Engineering sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Material Engineering holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Car Mechanic has 27 ratings behind it against 2, so its average is the more settled of the two.

Car Mechanic ships an update every 6 weeks, Material Engineering every 3 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
