The System

One app for the whole prep

Coaching, programming, nutrition, peak week and the stage, every tool a serious competitor needs, engineered into one private, on-device workflow.

01
AI Coach

Ask your coach anything

A Claude-powered coaching chat with knowledge retrieval. Drop in your coach's files and protocols, then ask for guidance on cutting, carb-ups, sodium-water manipulation, or why your scale moved. Context-aware answers, on tap.

Workout generator: body parts, equipment, intensity and training goal

Workouts that adapt to your history

Generate goal-specific programs by body part, available equipment, duration and intensity, then let progression do the rest. The engine reads your logged sessions and PRs to drive the next block of overload.

  • Goal-specific
  • Equipment-aware
  • Auto-progression

Prep Tracking

Track the whole picture

Check-ins with trend analysis flag whether you're on-track, too-fast or too-slow. A muscle-recovery body map, conditioning scores, posing logs, meal plans and personal records keep every variable of your prep in one command center.

  • Trend analysis
  • Recovery body map
  • Conditioning score
  • Personal records

Wired into Apple Health

Weight, body-fat %, macros and water flow in and out of HealthKit, while sleep, HRV and resting heart rate give you a read on recovery. Your weekly volume and conditioning sit beside the metrics that actually drive a peak.

Point. Shoot. Train.

Walk into any gym and point your camera at a machine. Claude vision identifies the equipment so your generated workout uses exactly what's in front of you, no more skipping movements because you don't know the rig.

Why Coach's Vault

Stop running prep on scraps

Spreadsheets, camera-roll screenshots and three half-used apps don't win shows. One purpose-built command center does.
