The Pearl Model S and Pearl Model S 2022 are both excellent standalone scales. The two may look almost identical when switched off, but each possesses many unique features.
First and foremost, both scales are as accurate and fast as one another. The Pearl Model S 2022 is a reimagined version of our original Pearl Model S scale (first released in 2019) with improvements based on suggestions from our team and community.
Both scales are updated through the Acaia Updater app. We periodically release firmware updates for many of our products and announce updates on our social media. The Pearl Updater is used solely for the original Pearl scale that is still supported by our development team.
