Verdict
The clearest difference is rating: 5F Freight at 4.6 against OTR Diagnostics's 4.0. 5F Freight also leads on monetization model (free vs free with in-app purchases) and ratings volume (1.7K vs 99). OTR Diagnostics's advantage is review sentiment (55% vs 23%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
5F Freight holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: 5F Freight has 1.7K ratings behind it against 99, so its average is the more settled of the two. Written reviews complicate that: 55% of OTR Diagnostics's written reviews are positive against 23% of 5F Freight's, so the app with the better star average is not the one people write more warmly about.
OTR Diagnostics ships an update fortnightly, 5F Freight every 10 days. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
