Tap-to-Interact Launch Issues / App Clip Unavailable

How to Perform "Tap-to-Interact"

When you are interested in the current content on the device, simply use an NFC-enabled phone to lightly tap the blank area on the right side of the device to quickly launch the Dot. App for viewing or actions.

During "Tap", the device does not need to wake up or be connected to power.

To activate and use Dot. series devices or features, please install the Dot. App first.

Download the App

iOS Users: Please go to the App Store to download.
Android / HarmonyOS Users: As the app store review is in progress, you can click this link to download the installer for now. The specific release time depends on each marketplace’s review progress.

After completing activation according to the instructions, you can remotely control devices from anywhere via the Dot. App, including content updates, task configuration, interval adjustments, device sharing, reboot, and sleep operations.

Compatibility

iOS: iOS 17 and later
Android: Android 12L and later

“App Clip” unavailable

If you encounter "App Clip unavailable" after a tap-to-interact action, it indicates that you have not yet installed the Dot. App. After installing the latest version of the app, you can use tap-to-interact functionality.

This error occurs because the current App Clip size exceeds Apple's system size limit for "launching an App Clip without installing the main app." We are actively working to reduce the App Clip size so it can be invoked directly without requiring the main app installation.

Cannot launch

iPhone

If tap-to-interact fails to launch the App Clip on iPhone, try locking your iPhone, unlocking it again, then move the iPhone in an upward motion and approach the right side of the device. This typically triggers the App Clip correctly.

This issue is generally caused by iOS system limitations. When you attempt to tap multiple times from the same App Clip source, iOS may block subsequent launches. Only after locking the screen and approaching again with a more pronounced movement will iOS invoke the App Clip again.

If you are using an iPhone intended for Mainland China, verify that NFC is enabled in Settings → General.

Android

If tap-to-interact does not redirect correctly on Android, ensure that the Dot. App is installed, NFC functionality is enabled, and you are aware of your Android device's NFC sensing area location.

Bring the NFC sensing area close to the blank area on the right side of the device to invoke the content.
