Verdict
The clearest difference is rating: OBD Quest at 5.0 against OBDocker's 4.2. OBDocker's advantage is ads (none vs shown) and ratings volume (17 vs 1). On price, update cadence, in-app purchases and monetization model 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. OBDocker sells 7 in-app purchases, starting at $2.99 per month and OBD Quest sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
OBD Quest holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: OBDocker has 17 ratings behind it against 1, so its average is the more settled of the two.
OBDocker ships an update fortnightly, OBD Quest every 3 weeks. The most recent releases landed on September 22, 2026 and June 1, 2026 respectively.
