About SparkyFitness

SparkyFitness is a self-hosted, privacy-focused fitness tracking platform for individuals and families who want to log nutrition, exercise, hydration, sleep, fasting, mood and body measurements while keeping the data on infrastructure they control. The README presents it as an alternative to commercial apps such as MyFitnessPal, Flo and Hevy.

The system has three parts: a backend server that provides the API and stores data, a web-based frontend, and native mobile apps for iOS and Android. Core features include goal setting, daily check-ins and interactive charts, and the project pitches AI-assisted health coaching. The README is translated into many languages, which reflects an international community.

The code is written in TypeScript and released under a license that GitHub lists as 'Other', so confirm the terms in the repository. It is designed to be self-hosted, and it suits households who want shared health tracking without sending personal data to third-party services.
