Case Study: Flo Health achieves a 500% productivity boost and streamlined localization with Smartcat

How Smartcat helped streamline localization of the Flo app

Flo Health, maker of the Flo app used by over 100 million people, struggled with inconsistent translation quality and no reliable pool of freelancers when relying on Upwork for localization. To translate articles and localize the user interface they adopted Smartcat — using the Smartcat Freelancer Marketplace, Vendor Management features and the platform’s open API (integrated via Serge) to onboard and manage vendors more reliably.

Smartcat streamlined Flo Health’s workflow, cutting their localization process from 38 steps to 6 and enabling a 500% productivity increase (300 new articles in the first month versus 40–50 previously). The platform improved consistency, reduced complaints about non-gender-neutral language, and sped up UI fixes; Flo Health now validates vendors through Smartcat-supported QA point-cuts (30% → 15% → 5%) and tracks cost-per-word and user reviews to measure impact.
