Background
The Acaia Pearl is a bluetooth-enabled coffee scale designed to help cafés and coffee enthusiasts track and repeat weight-related brew parameters. Introduced on Kickstarter in 2013 and general sale in 2014, it offers features such as 0.1-gram accuracy, integrated timer, rechargeable battery, and bluetooth app connectivity.
Acaia released a revised version of the Pearl in 2021. The only differences between the original and 2021 revisions is the change from Bluetooth 4.0 to Bluetooth 5.0 and the switch from the Pearl Updater app to the Acaia Updater app.
Compatible Apps:
- Acaia Coffee
- Brewmaster
- Brewbar (for commercial environments with multiple scales)
- Pearl Updater (pre-2021 hardware) or Acaia Updater (2021-present hardware)
The Pearl charges via Micro-USB or USB-C, depending on hardware revision.
