    "why": "Tracking nutrition, exercise, sleep, cycle and medication separately usually means paying for several different subscriptions with no single view across them. SparkyFitness puts all of it on one self-hosted server (run via Docker Compose) and lets a family split access with granular permissions. It syncs steps, workouts and sleep automatically from 8+ services (Apple Health, Fitbit, Garmin, Oura and more), and a beta conversational AI (SparkyAI) can log a meal from an uploaded food photo.",
    "take": "It openly admits it's source-available, not open source — and backs its value claim with a public comparison table against several paid alternatives' subscription costs.",
    "build": [
      "Consolidate several health-app subscriptions into one self-hosted server the whole family shares",
