Frequently Asked Questions

Which refractometers are supported?

Brewmetric works with any coffee refractometer on the market (VST, Atago, DiFluid, etc.). Because you enter your measured TDS manually into the app, Brewmetric is hardware agnostic.

Do I need a subscription?

No. Brewmetric is a one-time purchase. There are no subscriptions, no recurring fees, and no in-app purchases required to unlock core functionality.

Does Brewmetric require an internet connection?

No. Brewmetric is a 100% offline application. All your data, recipes, and computations happen directly on your iPhone, ensuring maximum privacy and instant performance no matter where you are brewing.
