Niban

The app icon is a blue "2". Try placing it next to the "Ichiban" (with "1") icon on your home screen for easy access. Just like a TV remote, simply tap the numbered icon to start a video call - tap "1" for one person, "2" for another. For Beginners: 1) For senior beginners, we recommend having a family member help with the initial setup. 2) Let them know: "I've added another contact. You can now video call with [name]" and "Look for the blue '2' icon." 3) After setup, please help them test the connection and guide them through their first calls. Setup and Operation: Same simple process as "Ichiban" app.
