Verdict
The clearest difference is rating: Torque Pro at 4.3 against YMOBD's 2.9. Torque Pro also leads on update cadence (fortnightly vs every 5 weeks) and ratings volume (520 vs 84). YMOBD's advantage is monetization model (free with in-app purchases vs subscription) and ads (none vs shown). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. YMOBD sells 4 one-off in-app purchases and Torque Pro sells 5 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Torque Pro holds the better App Store score, 4.3 against 2.9. That said, the two scores are not equally well evidenced: Torque Pro has 520 ratings behind it against 84, so its average is the more settled of the two. Written reviews complicate that: 34% of YMOBD's written reviews are positive against 6% of Torque Pro's, so the app with the better star average is not the one people write more warmly about.
YMOBD ships an update every 5 weeks, Torque Pro fortnightly. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
