For the best experience with the smartwatch we recommend using the tuw™ Smartwatch App for Android or iOS and following the prompts and setup process via the App. You can find the App in the Google Play Store for Android devices such as Samsung, Huawei, or LG, or the Apple App store for iOS devices such as iPhone or iPad.
