SparkyFitness

SparkyFitness supports local accounts plus OIDC single sign-on for hooking into an existing identity provider, TOTP-based 2FA, and Passkey login for passwordless access. All three can be combined, and administrators can enforce MFA per user.

Yes — SparkyFitness ships native iOS and Android apps. The iOS app reads from Apple Health and the Android app uses Google Health Connect, so steps, workouts, sleep, and body measurements from your phone sync automatically. Built-in integrations also cover Fitbit, Garmin Connect, Withings, Polar Flow, Hevy, and Strava.

Each family member gets their own profile with separate goals, logs, and reports, but they share the same self-hosted server. The feature is currently in beta, so the docs note it may be incomplete — expect rough edges around invitations and shared settings.

Foods can be looked up from OpenFoodFacts, USDA, Fatsecret, Nutritionix, Mealie, Tandoor, Norish, and the Swiss Food Database, so you can usually find branded and restaurant items without typing them in by hand. For exercises, the project ships the Free Exercise DB and Wger integrations, plus a custom exercise library.

SparkyAI is an optional beta feature, so the rest of the app works without it. When enabled, you can log food, exercise, body stats, and steps through a chat interface, and upload a meal photo for automatic macro estimation. It also keeps conversation history, so you can ask follow-up questions about your trends.
