Abstract: An electronic system (1) comprises an electronic device (2) for gathering data from an inhaler (3) which is configured to dispense doses of a pharmaceutical formulation stored in a medicament reservoir. The system (1) further comprises an evaluation unit (9) being configured to receive and evaluate the gathered data in order to determine adherence to prescription data and/or to determine the number of doses having been dispensed or remaining in the inhaler (3) and a display (8) for visualizing the evaluated data. The electronic device (2) comprises a wireless interface (4) for receiving wireless data from the inhaler (3) via a wireless connection an input interface (5) for receiving manual input data and an acoustic or visual interface (6, 7) for receiving acoustic or visual data of the inhaler (3).
