Built for
serious athletes.

Every feature designed to make you stronger, faster, and smarter about your training.

AI Program Generation

Programs built around you. Not templates.

Machine learning analyses your training history, recovery patterns, and goals to generate fully periodised programs. Accumulation, intensification, deload — structured across weeks, not guessed at. Programs adapt as your data changes. No two athletes get the same output.

The AI considers your experience level, training frequency, equipment access, and goal — whether that's building muscle, getting stronger, or preparing for competition. Volume targets are derived from your personal response data, not population averages.

AI Coaching

Your coach knows your body.

A real-time coaching engine powered by your performance data, recovery scores, and training history. It reads your readiness, analyses your training load, and delivers specific guidance — not generic motivation.

The coach integrates HealthKit biometrics (HRV, resting HR, sleep), your training volume and intensity trends, and personal response patterns. It tells you which muscle groups to hit, what RPE to target, and when to back off.

Live Workout Tracking

Every rep. Every set. Every PB.

Full workout logging with auto-populated weights from your history, real-time rest timers, RPE tracking, and automatic personal best detection. Your training data builds your intelligence.

Tracks sets, reps, weight, RPE, tempo, and rest periods. Previous performance is shown inline so you know exactly what to beat. PBs are flagged instantly. All data feeds back into the AI coaching and volume prescription systems.

Sprint & Run Tracking

Structured speed work. Tracked.

Sprint intervals, tempo runs, and structured running sessions with GPS tracking and interval programming. Run training with the same precision as your strength work.

Build interval workouts (100m sprints x8, 400m repeats, tempo runs) with programmed rest periods. GPS tracks pace, distance, and splits. Heart rate integration from Apple Watch for zone-based training.

Recovery Analytics

Know when to push. Know when to pull back.

HR kinetics, recovery rate analysis, and readiness scoring powered by your Apple Watch data. Every training decision informed by real biometric data, not guesswork.

Analyses intra-session heart rate patterns — peak/trough detection during sets and rest. Calculates recovery rate trends across sessions. Feeds into a readiness score that the AI coach uses to adjust your daily programming.
