Spot-On is a versatile communication app that allows you to stay connected with your contacts through several different channels. You can send instant messages, emails, and even share files with your contacts. Additionally, it lets you create a chatroom for group conversations.

The app features a main window organized into different categories, which you can access using the tabs. These categories include Buzz, Chat, Email, Listeners, Neighbors, Search, Settings, StarBeam, and URLs.

When you launch the app for the first time, you will be prompted to configure it by entering your name and setting up a security system. You can choose between setting a passphrase or defining a question/answer security system, which is required for public key generation. The app also allows you to customize the default cipher and hash types, congestion algorithm, and SSL key size through combo menus. To make the setup process easier, Spot-On provides a wizard that guides you through the steps.

Spot-On uses the Echo Public Key Sharing system to create a secure community. This means that a community is defined by a pair of encryption and authentication keys that can be exchanged via the community if desired.

Spot-On is not a simplistic communication app, but if you are looking for an app that offers advanced security and don't mind its complexity, this app could be a good fit for your needs.
