# fitdays: reconstructing a smart-scale cloud client

> fitdays recreates read-only access to the Fitdays smart-scale cloud API from traffic observed in the vendor app. Its asynchronous Python client logs in with the service's password digest, follows regional redirects, renews sessions, and retrieves scale, profile, and body-composition measurement records.
