For which mode do I need a computer?

Spooky2 Scalar offers three ways to apply the scalar field: pure scalar, molecular scalar, and Rife scalar. For pure scalar, you don't need a computer. Just set up and tune the scalar. And put substance on receiver box to absorb the benefits of that chemical. But for Rife scalar, you should use a computer, allowing you to operate Spooky2 software and run the programs you need.
