Acaia offers a number of apps that can be used with the products and are available for both Android and Apple. In addition to apps for updating the software on the scales, there are some apps that have been developed to help you brew your coffee or espresso. These currently include Acaia Coffee, Brewmaster, Brewguide and Brewbar. Which app is the right one for you depends on your Acaia model on the one hand and on the functions you want from the app on the other. For example, while the Brewguide app was specially developed for the Acaia Pearl S, the Acaia Coffee app is perfect for getting started and for use with all Acaia products.
