With this WPM app, the user can master the settings of maximum 4 stages of extraction pressure-time profiles for your favourite taste of espresso. It allows you to provide 4 sets of sequential parameters of pressure levels (1 the lowest to 7 the highest) and time duration (0-15 seconds) for the process of coffee brewing. Besides, the user can also preset the pre-infusion level, coffee brewing group temperature as well as the steam duty at fingertips. All these settings can then be wirelessly sent to the machine for activation accordingly. After all, the user can save all those data with corresponding line curve shown into favourite recipes that can be retrieved again easily. Other data such as taste definition, the name of the bean and a photo of coffee made can also be put into the diary for the record. Remarks: The app works with designated WPM machine only.
