Merge connects Android smartwatches to iPhones, and Apple Watches to Android phones, allowing users to choose their preferred devices without ecosystem limitations. The platform enables cross-platform compatibility between wearables and smartphones.

Merge enables users to sync notifications, calls, fitness data, and music controls between devices. It supports receiving Android notifications on Apple Watch, replying to messages, controlling media playback, and syncing Apple Watch's health data to Health Connect compatible apps on Android.

The system works through seamless Bluetooth communication between devices. Users download the Merge app on their Android phone (via Play Store or QR code) and the Merge app on their Apple Watch (via App Store), then follow the setup process to connect the devices.

Benefits include using Apple Watch with Android phones, connecting Wear OS watches to iPhones, and the ability to use one watch with two phones simultaneously (both iPhone and Android). Users can maintain their preferred wearable when switching phone ecosystems.

The product targets users who want to use Apple Watch with Android phones or Wear OS watches with iPhones, particularly those using multiple phones or switching between ecosystems. It supports various Apple Watch models from Series 4 through Series 10, including SE and Ultra models.
