The Trek Accessories App and Trek CarBack Radar can detect rear approaching vehicles from up to 240M, with vehicles first appearing with an audible beep and a visual indicator at the bottom of the App screen. Once the detected vehicle approaches to within 150M, the vehicle is shown on screen in real time.

Verdict
The clearest difference is review sentiment: RAGBRAI at 100% against Trek Accessories's 36%. RAGBRAI also leads on update cadence (every 2 days vs every 3 months). Trek Accessories's advantage is rating (4.7 vs 4.0) and ratings volume (204 vs 8). On price, ads, 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. Neither carries in-app purchases, so what you see is what you pay.
Trek Accessories holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Trek Accessories has 204 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 36% of Trek Accessories's written reviews are positive against 100% of RAGBRAI's, so the app with the better star average is not the one people write more warmly about.
Trek Accessories ships an update every 3 months, RAGBRAI every 2 days. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
