The beauty with Bubble is that the app tracks the sit to the minute allowing parents to pay their babysitter in a tap at the end.
The removes the hassle and awkwardness of fumbling around for exact change (sometimes after a long-overdue night out!).
And we find that both parents and sitters love the convenience and simplicity of cashless payment.
Payment on Bubble is completed in a tap of the app - cash payments are not accepted.
