Lean canvas

1. Problem​

  • I struggle maintaining fitness, nutrition, and weight — they're all connected to life stresses.
  • History shows a repeating cycle: stress → less fitness → poor nutrition → weight gain.
  • Current apps don't predict or prevent these cycles; they just track after the fact.
  • Need a personal coach that knows me intimately and provides proactive support.

2. Customer segments​

  • People who struggle with fitness cycles — recognise stress patterns derailing health.
  • Runners seeking personal coaching — want adaptive support, not just data tracking.
  • Self-hosting enthusiasts — want control over personal health algorithms.
  • Long-term health thinkers — willing to collect 10+ years data for prediction.

3. Unique value proposition (UVP)​

"A deeply personal fitness coach that predicts your cycles and speaks in your own voice."

  • Proactive intervention before negative cycles start, not reactive tracking after problems occur.
  • Transparent cost structure (host it yourself, avoid recurring subs).
  • Flexible to grow into nutrition, recovery, and wearables integration.

4. Solution​

  • Stage 1: Sync running activities (Strava + TrainingPeaks history). Production-ready foundation with splits, thumbnails, CSV export.
  • Stage 2: iOS app integrating Apple HealthKit.
  • Stage 3: Replace secondary apps (HealthFit, Athlytic, WaterMinder, MyWeight).
  • Stage 4: Food tracking for key metrics (calories, sugar).
  • Stage 5: Apple Watch app for runs + music capture.

5. Channels​

  • YouTube dev series (“Too Many Fitness Apps?”).
  • GitHub / GitLab repo with full code and logs.
  • LinkedIn updates to professional/fitness audiences.
  • Word-of-mouth from runners and devs experimenting.

6. Revenue streams​

  • Primary: None (personal project, free + open source for now).
  • Potential: Support services, premium hosting templates, or sponsorship.

7. Cost structure​

8. Key metrics​

  • Number of activities synced (accuracy + reliability).
  • Latency of new activity sync (<30s via webhook).
  • DB performance (API <50ms, minimal requests).
  • User metrics: daily/weekly active (for later stages).

9. Unfair advantage​

  • Deep hands-on experience with Kubernetes, GitOps, and AI-assisted coding.
  • Personal frustration gives strong founder-market fit.
  • Blend of coaching mindset + tech expertise allows unique framing (helping others learn from mistakes).
