Feature Overview

Everything you need.
Nothing you don't.

FitKind stays tracker-first: logging, PRs, and offline reliability lead today. GPS and wearables are on the roadmap in the power layer — coming after launch, not in the app yet.

Readiness, not just activity

Fire Score tells you how ready you are today — not just how much you lifted last week.

  • Fire Score: 0–100 daily readiness built from strain, sleep, HR, and HRV
  • Graceful degradation — score always available even with partial data
  • Apple HealthKit integration (iOS): sleep, HR, HRV, active energy, body weight
  • Google Health Connect integration (Android): equivalent permissions
  • Historical import: up to 6 months of past workout data on first connection
  • Hydration tracking with daily targets and intake logging
  • Duplicate detection on health imports (prevents double-counting)
