The dawn of the personal computer era gave birth to a new type of criminal, the hacker. Today there is a new even more attractive target for hackers to exploit, the Android smartphones. These devices allow us to use internet, camera, GPS tracking, and more features. Smartphones also contain detailed records of our contacts and SMS. The hacker then uses these records for committing identity theft. Hence to provide security to Android smartphone we have developed a circular screen locking application.

This helps user to know who is calling and sending messages on their device. Hence this application satisfies the need of today's users & applications.
