Muscle Clock

Fast, companion-style muscle readiness tracking - no subscriptions, no in-app purchases, no lock-in.

Muscle Clock is a fast, companion-style app that helps you track muscle recovery and readiness over time - without replacing your workout app.

Log training in seconds: • Choose an exercise, a body part or a specific muscle • Pick an effort level (Warm-up → All-out) • Muscle Clock estimates recovery and shows what’s likely ready today

See recovery clearly: • A muscle readiness dashboard with simple status and “ready in…” timing • A visual recovery view (front & back) for quick understanding • Searchable history of what you logged

Plan ahead: • Time travel forward or backward to preview recovery tomorrow (or revisit the past)

Built to stay lightweight: • No subscriptions and no in-app purchases • No accounts • No registration • Data stays on your device • Easy JSON import/export - your data, your control • Loads fast (no splash screen)

Recovery estimates are a training signal - not a diagnosis. Always listen to your body and adjust training based on how you feel.
