# Ultimate Diesel Builders Guide vs ATV Trader

The clearest difference is in-app purchases: ATV Trader at none against Ultimate Diesel Builders Guide's 10. ATV Trader also leads on update cadence (every 10 days vs every 3 months) and ratings volume (2.1K vs 8). Ultimate Diesel Builders Guide's advantage is ads (none vs shown) and iOS requirement (10.0 vs 16.0). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. Ultimate Diesel Builders Guide sells 10 in-app purchases, starting at $7.99 per 6 months. ATV Trader asks for nothing beyond the download.

Ultimate Diesel Builders Guide holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: ATV Trader has 2.1K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 33% of Ultimate Diesel Builders Guide's written reviews are positive against 36% of ATV Trader's, so the app with the better star average is not the one people write more warmly about.

Ultimate Diesel Builders Guide ships an update every 3 months, ATV Trader every 10 days. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
