A dispensing apparatus for use with a replaceable unit dose package has at least one cavity sealed by a membrane, wherein the cavity contains additive materials to be dispensed. The dispensing apparatus is configured for use, for example, in a washing machine, wherein the washing machine has a plurality of cycles. The dispensing apparatus comprises a dispensing director having a dispensing signal generator and a monitor for distinguishing among a plurality of washing machine operating cycles. The dispensing apparatus further includes an actuator in communication with said dispensing director and configured to selectively electromechanically open the membrane in response to a dispensing signal, thereby releasing additive materials from said at least one cavity. Also disclosed is a disposable unit dose package for use in a washing machine and with a dispensing apparatus having a dispensing director and an electromechanical actuator in communication with said dispensing director. Still further disclosed is a kit, system, and method of dispensing laundry additive materials into a rotating washing machine having a drum.
