Short answer
The Amazon Relay app is Amazon's mobile app for iOS and Android. Drivers for approved, onboarded Relay carriers use it to see their schedule, check in and out at facilities, follow truck-friendly routes, get load instructions and report issues.
What is the Amazon Relay app?
It's Amazon's mobile app for Relay, on iOS and Android. Amazon's mobile app post says it's "used by hundreds of thousands of truck drivers worldwide."
It isn't open to everyone. "Only drivers that work for approved and onboarded Relay carriers can use our trucking app." A driver gets in by invitation from their carrier.
Carriers use it too. Amazon's Prime Day post says you can "Search and book freight anywhere you get a phone signal." You can also apply to Relay in the app and track your application's progress.
The same app post says truckers rate Relay 4.7 out of 5 on iOS and 4.6 on Android. Ratings change, and that post was last updated in February 2026.
What can drivers do in the Relay app?
From Amazon's app post and the Relay home page, drivers can:
- Onboard to Relay and see their schedule, with new loads added as they come
- Do asset inspections
- Get step-by-step load instructions, including pickup, drop-off and in-yard steps
- Follow truck-friendly routes that avoid "residential areas and low-bridge locations"
- Watch route weather. The forecast keeps updating until the end of the trip, with alerts for new severe weather
- Get cancellation alerts within 5 hours before the scheduled time
- Add stops for fuel, food and parking while planning a trip
- Review load history
- Chat with Relay Assistant and report issues
Who can use the app, and how drivers get added, is in Amazon Relay for drivers.
How does check-in work with the Relay app?
Mostly automatically. The Relay home page says: "Our automated facility check-in/out process and electronic in-yard instructions reduce driver dwell time at the gate and in the yards."
Amazon's yard technology story describes it at the gate. "Large monitors outside the truck's window show the driver where to go, such as which dock door to back into." The "instructions are provided on the driver's Relay mobile app, and the gate automatically opens."
Check-in time matters for your score. Amazon's performance score guide says on-time is calculated "based on the check-in timestamp at the site."
One hard stop for California: Amazon's CARB post says "Trucks that travel through California for Amazon loads will be rejected at check-in without valid certificates."
Amazon publishes no early or remote check-in policy.
Where are bills of lading in the Relay app?
Amazon's yard technology story says the system uses "electronic proofs of delivery and bills of lading." Amazon's load tracking post says carriers can play back a trip, including "document uploads (e.g., bills of lading)."
Amazon doesn't publish what to do when a BOL doesn't show in the app. For a load in progress, the Relay Operations Center is the place to ask. It's open 24/7 through the Relay portal or Relay mobile.
How do drivers get help through the app?
Through Relay Assistant and issue reports. The app post says drivers can "request support from Relay Assistant throughout their trip," an AI chat tool. They can report non-traffic issues causing a delay, and "If they have a breakdown or mechanical issue, they can report it in the app."
Amazon's September 2026 update says that when Relay Assistant can't resolve an issue, "it connects you to a human operator with your conversation's full context."
There's no phone number to fall back on. Amazon's Relay FAQ says Amazon Relay "doesn't have an official contact phone number."
What app rules affect your scorecard?
Two things to drill into every driver:
- Keep the app open with location on. The load tracking post says tracking needs "location services are turned on in the Relay app" and that "the app is open while a driver is executing Relay loads."
- Run every Amazon load in the app. Amazon's performance score guide says "Amazon requires all loads to be executed using the Relay mobile app."
App usage is one of the four metrics in your Relay performance score. Our scorecard guide explains how it works with the other three. Amazon's Relay driver 101 course also covers Relay app usage, per its Learning Center post.
If an app usage or late arrival hit lands on your scorecard and you think it's wrong, our free Relay dispute letter tool lets you tick what's true and copy a letter to submit. Amazon decides.
Is the Relay app not working?
Amazon doesn't publish app troubleshooting. Its only published fixes are for logging in, in the FAQ:
- Reset your password on Amazon's account recovery page, using the email you sign into Relay with.
- Make sure it's the same email you first registered with.
- If a page keeps spinning, try a private window, clear your cookies or switch browsers.
For a problem on a live load, contact the ROC through the portal. And don't hand your login to anyone. Amazon's geospoofing post says: "Don't share your login information with anyone."
What doesn't Amazon publish about the Relay app?
- An early check-in policy or window
- Remote check-in rules
- How to fix a BOL that doesn't show in the app
- How the app behaves with no signal
- Troubleshooting for "app not working," beyond the login steps
Where does NudoIQ fit?
NudoIQ isn't a phone app and doesn't replace the Relay app your drivers use. It's an independent Chrome extension for the Relay load board, not affiliated with Amazon, that runs in desktop Chrome and on Android through the Lemur browser (see our Android setup page), but not on iPhone. On the board it shows net and net per mile under the price on every load card, and it can auto-refresh the board for you. It's free for 7 days with no card needed to start, then $49.99 a month.
