Brewbar is an iOS tablet app in beta, download the app here. It is a brew station management tool. It connects up to four scales and three brew stations at a time, displaying them on one tablet.

Requirements for the app include:

  • iOS tablet with iOS 9 or 10 and Bluetooth 4

  • At least one pearl (multiple preferred) with latest firmware update

The app has the ability to connect with both Pearl and Lunar scales, the Baratza Sette 270W, and the Fellow Stagg EKG+ kettle.



The Brewguide app exclusively connects with the Pearl Model S and Pearl Model S 2022. One of Brewguide’s main features is the easy transfer of recipes from the app to both scales. The app also features some settings that  are available to be changed through the app, including turning on/off modes, units, temperature (for recipes), auto-off timer, button sound, and your hello message. If you do not have a Pearl Model S or Pearl Model S 2022, you are still free to download the app and browse the database of both roaster and consumer recipes. Recipes can be accessed and shared through both links and generated QR codes.


What's the difference between the Acaia Coffee and Brewmaster Apps?

While both apps are similar in some of their premises, there are a few differences. Acaia Coffee provides a way to share brewing info across the community, while Brewmaster is as close to a straight data logger as we can get.

Brewmaster is a logging app that is designed to be quicker for brewing workflow. Two screen touches from the home screen of the app will get you recording the output of the scale. The graphing is a bit more detailed than the Acaia Coffee app, too.
