It is important to note that this app is not an independent dictionary, nor is it the official app of Thi Viện. It does not have offline lookup, word saving, or pronunciation features. However, it does have some useful functions that allow users to lookup words from other apps, such as browsers. Users can highlight a character and share it with the app to look it up, or select the "Tra H-V" option if their device is running Android 6.0 or later. Additionally, for devices running Android 7.0 or later, users can use the Quick Settings tile to search for words from anywhere on their device. If the device has a browser that supports custom tabs (such as Chrome, Firefox, Firefox Focus, Samsung Internet, etc.), the app will open the website in a lightweight custom tab.
