You don’t need a registration or SMS authentication to start. All you need is to install the app.

There is no cumbersome setup. You can easily pair-up via email or QR code and start chatting privately in a minute.

You can easily create a private chatroom for just the two of you.

All elements you'd want for communication - text, location information, photographs, and stamp - are available. Combination such as text + location information, text + photo, and text + stamp can be done as well.

You can save the contents that could not be sent. You can also check the status of the partner and if (s)he had read the messages.

You can set the background image and notifications for each chatroom, and things like font size can be set across the app.

You can create multiple private chatrooms, that allows you to enjoy private and separate communications with your family, best friend, girlfriend, business partner, or anyone really!

You can create shortcuts to chatrooms on the device's home screen. Shortcut icons and titles are customizable.

You can configure the security settings at friend level in addition to the passcode for the app. Nobody else can see the friend you've set the security setting for unless you enter the unlock code.
