A method for evaluating the pump actuation for a pump dispenser that includes two sub-units which can be moved manually towards one another and a pump which has a pump chamber that can be made smaller by moving the sub-units from a first end position into an actuated second end position. The force with which the sub-units are moved towards one another is detected by a force sensor during movement of the sub-units. The curve over time of the detected force is evaluated such that an increase in force is identified which is characteristic for reaching the actuated second end position. Depending on whether the increase in force was detected, a signal which is characteristic for the result is haptically, acoustically and/or visually output and/or transmitted via a wireless interface to an external display apparatus, by means of an output device.
