Your Refundable Paywall. Your RoboCash.

We made this easy. If you answer a cash call, you decide if it is spam by hanging up before 25 seconds.

Take back control over your time
Easy to use
Try it yourself!

Bad callers lose their deposit, good callers get a full refund!

Unknown callers must deposit $0.05 before they can call you. If you answer and the call lasts longer than 25 seconds, they get a full refund! If you hang up early, they lose their deposit to you.
