Acaia Pearl vs Timemore Black Mirror

The reference standard vs the value champion. Both weigh to 0.1g with a built-in timer, so on raw accuracy they're closer than the price gap suggests — the Timemore Black Mirror Basic 2 costs roughly a third of the Acaia Pearl and matches it for espresso dosing and pour-over. What the extra money buys on the Pearl is the fastest, most consistent auto-tare and refresh, the Bluetooth app with real-time flow-rate logging, and a build that shrugs off years of daily brewing. If you want to log and dial in your pours like a competition barista — or you just want the scale everything else is measured against — the Pearl earns it. If you want 95% of the performance to nail your ratio every morning and would rather put the savings toward better beans or a grinder, the Black Mirror is the smarter buy.

Fellow Tally Pro vs Acaia Pearl

Two premium precision scales with opposite philosophies. The Acaia Pearl is the connected scale — its edge is the Bluetooth app that logs real-time flow rate and brew curves, the standard specialty cafes benchmark against. The Fellow Tally Pro is deliberately app-free: it puts everything on the scale itself, including a Brew Assist mode that guides your pour and an aggregate weight mode for building a recipe, wrapped in Fellow's signature matte design. Both are 0.1g accurate. Choose the Pearl if you want to record and analyze your brews as data. Choose the Tally Pro if you want a beautiful, self-contained scale that coaches your pour without ever opening your phone.
