Relay Autobooker Cardamon works on Android phones through Kiwi Browser, which can run Chrome extensions. It does not work on iPhone or iPad, because no iOS browser supports Chrome extensions. iPhone users can run the extension in Chrome on a desktop or laptop that stays on, and manage trips from the Amazon Relay app on the phone.

Does Relay Autobooker work on Android?

Yes. Kiwi Browser is a Chromium-based Android browser that runs Chrome extensions, so the extension works on Android phones with the same features you get on desktop: the free Smart Refresher, audio alerts when new loads appear, and the Premium auto-booking and filters if you subscribe. Android support shipped in version 8.0, back in April 2025. One catch: Kiwi left the Google Play Store, so you install it from the APK on GitHub first, then add the extension from the Chrome Web Store inside Kiwi. The step-by-step walkthrough, including which APK file to pick, is in How to install on Android (Kiwi Browser).

Why doesn't it work on iPhone or iPad?

No browser on iOS can run Chrome extensions. The Chrome app on an iPhone shares a name with desktop Chrome, but it runs on Apple's WebKit engine and has no extension support. Relay Autobooker is a Chrome extension, so there is nowhere to install it on an iPhone or iPad. No iOS browser fills that gap the way Kiwi Browser does on Android.

What can iPhone users do instead?

Let a computer do the booking while the phone stays in your pocket. The practical setup:

• Run Chrome on a desktop, laptop, or mini PC that stays on, with the Amazon Relay load board open
• Turn off sleep in the power settings so the browser keeps refreshing
• Set your payout, Max Stops, and Stem Time filters so the extension only books loads you would take yourself
• Check booked trips in the official Amazon Relay app on your iPhone, the same way you do now

A load the extension books lands in your Relay account like any booking you made yourself, so the trip shows up in the app on your phone even though the click happened on the computer at home. If that computer reboots for Windows updates, the extension stops with it, so disable automatic restarts or glance at it once a day.
