From the creator of Quick Circle Apps

Quick Circle is a powerful concept. It allows you to do simple and quick action using one hand only. However, Quick Circle lack the option to lock private apps like dialer, calendar (Quick Circle Apps).
Quick Circle Lock is the answer for that. It gives you the option to lock privates apps using Knock Code.

We don't send your knock code!!!
