Expo Router Universal Links: Deep Link Setup in 2026

If your app still opens with myapp:// URLs in 2026, you are leaving the front door locked. Users tap an https link in WhatsApp, Slack, or Gmail and end up on your marketing site instead of inside the app, three taps away from where they wanted to be.

This guide walks through the full Expo Router universal-link setup that ships in Expo SDK 53 and React Native 0.84. By the end you will have an iOS app that opens from https://yourdomain.com/order/123, an Android app that does the same, and a web fallback for users who do not have the app installed yet. No native code, no Xcode juggling, no Android Studio side quests.
