Styrki: Gym & Run Tracker

Styrki is your AI training partner — a strength coach and multi-sport cardio tracker that learns how YOUR body responds and adapts every workout to match.

The exact weights, sets and reps for your body — recalculated every session as you get stronger. No guesswork, no cookie-cutter plans.

TRAIN SMARTER WITH AI
• Generate complete, personalized workouts in seconds
• Championship-proven periodization: volume, medium and intensity days rotated automatically
• Fatigue-aware programming that backs off when your body needs it
• An adaptive engine that calibrates weights, rest and progression to you — not population averages
• A coach that remembers: every chat and voice session feeds what it knows about you

YOUR STYRKI SCORE
• One number for the body you've built: activity, aerobic fitness, strength, recovery and wellness
• Watch it react to every session — and see exactly what moved it
• Rank against lifters like you, or keep it private

LOG LIFTS FAST
• The plate-tap logger: build your bar in two taps, log a set in one
• Automatic personal records — all-time, yearly and current, detected as you lift
• A rest timer that lives on your Lock Screen and Apple Watch
• Warmups, supersets, RPE and notes without breaking your flow

MULTI-SPORT CARDIO
• Record outdoor and indoor running, cycling, walking, hiking, rowing and swimming
• Activity-first start — pick Strength or Cardio, then the exact activity
• Live metrics that match the sport: pace, speed, power, cadence, splits, elevation and heart rate
• Connect FTMS smart bikes plus Bluetooth power, speed and cadence sensors
• Physiology and sport-specific personal bests — indoor and outdoor stay separate where it matters
• Sync with Strava, Polar, Oura, Apple Health and Bluetooth heart-rate straps

BUILT FOR IPHONE + WATCH
• Apple Watch companion, Live Activities and Home Screen widgets
• Apple Health: two-way workout sync and one-tap import of past cardio sessions
• Works offline — sets queue and sync when you're back
