Spot-On screenshotSpot-On is a free to use and open source research project. Free of advertisements, free of commitments, freedom of expression.

Spot-On is a communication program that contains an e-mail client, a messaging instrument, IRC chat client, and a file sharing client. This exploratory research project investigating a large range of cryptographic and communication algorithms. The application is composed of two distinct programs, a multi-threaded kernel and a user interface. The two files are developed in C++ and need the Qt framework as well as as an array of libraries. Qt versions 4.8.x and Qt 5.x are compatible. Qt variant 4.7.x is loosely compatible. The ARM architecture is also compatible.

E-Mail, Buzz, Messaging

Communicate with your friends ones. Firewalls? Try the almost rapid Poptastic feature. Spot-On, placing legacy e-mail protocols to use.

Spot-On is also an e-mail client.

Do you remember the IRC application? Even if you don't, with Spot-On, you can chat freely with other users. Live the nostalgia of netsplits and selfish channel operators.
