The library's planar world-angle rig becomes a genuine 3D anatomical model: skeleton.json holds bone-length profiles (real shoulder/pelvis widths, feet, neutral/female/male) and per-joint ROM; motions pose joints with anatomical angles (flexion/abduction/rotation from neutral standing) under a per-exercise orthographic camera, resolved by kinematics.py (3D FK, analytic two-bone IK with anatomical write-back) and validated against physiological ranges. All 20 sagittal motions were migrated by planar decomposition with 0.00 px golden parity against the old renderer — relabeled to true anatomy, since shading is now near-dark/far-light by camera depth rather than by limb suffix — and the face-on machines are re-authored honestly: Abductor/Adductor with real hip abduction (the foreshortened "frontal" profile is retired) and Rotary with genuine spine axial rotation. Figures gain articulated feet; profiles swap without touching a single motion script; --orbit sweeps the camera 360° while a motion loops. The in-app SwiftUI renderer (iOS + watch) is ported to the same model and consumes the exported motions verbatim; figure-fixtures.json pins its geometry to the Python pipeline within 0.5 px across every exercise, key frame, tween, and orbit sample. Also makes the watch bridge logger nonisolated for the newer SDK's stricter isolation checking. Claude-Session: https://claude.ai/code/session_01LEoff8bXGBS83tK1c55Mf7

# Workouts
|
||
|
||
A workout tracking app for iPhone and Apple Watch. Build workout splits, run
|
||
sessions, and track your progress — with your data stored as plain JSON files in
|
||
your own iCloud Drive.
|
||
|
||
## Key Features
|
||
|
||
- **Workout splits** — organize exercises into reusable routines with custom
|
||
colors, icons, and an activity type (strength, HIIT, cardio, …). Built-in
|
||
starter splits (Upper Body / Core / Lower Body
|
||
machine routines, plus an equipment-free **Bodyweight Core** circuit with its
|
||
own warm-up) appear automatically on first launch; editing one makes it your
|
||
own copy, and deleted starters can be restored from Settings.
|
||
- **Exercise library** — a bundled library of exercises to populate your splits,
|
||
authored in `Exercise Library/` with per-exercise setup, cues, mistakes,
|
||
progressions, and an anatomically-rigged 3D stick-figure visual system — covering the
|
||
bodyweight core moves plus the full Planet Fitness–style machine circuit
|
||
(presses, rows, pulldowns, curls, leg and hip machines).
|
||
- **Run a workout** — start a session from a split, then tap an exercise to run it
|
||
as a paged flow: a **Ready?** lead-in, count-up work phases, count-down rests, and
|
||
a **Finish** page — mirroring the Apple Watch. Swipe a row to mark it complete, or
|
||
swipe to edit its plan (sets/reps/weight or duration) and notes. End a workout early
|
||
from the **⋯** menu — **Save** keeps your progress (remaining exercises are marked
|
||
skipped) or **Discard** removes it.
|
||
- **Animated form guide** — every library exercise shows a looping stick-figure
|
||
demonstration on the run screen's bottom half, posed by real joint angles on an
|
||
anatomical 3D skeleton (complete with feet) and rendered live from the Exercise
|
||
Library's rig data with the working limbs highlighted — machine exercises
|
||
include schematic equipment (seats, bars, cables, roller pads) that moves with
|
||
the figure, and face-on machines show true hip abduction and torso rotation.
|
||
- **Machine comfort settings** — machine-based exercises remember your setup
|
||
(seat height, back-rest position, pin position, …), shown on the workout
|
||
screen and editable mid-workout; changes save back to the split for next time.
|
||
- **Progress tracking** — weight-progression charts per exercise across past
|
||
sessions.
|
||
- **Apple Watch companion** — starting a workout on the iPhone launches the watch
|
||
app straight into it. The watch lists your in-progress workouts; pick one, pick an
|
||
exercise, and run it as a paged flow: a **Ready?** lead-in, count-up work phases,
|
||
count-down rests with final-three-second haptics and auto-advance, and a **Finish**
|
||
page with **One More** and a **Done** that auto-completes after a countdown. A
|
||
phase-dot row (purple work, teal rest) tracks progress. Rest time and the
|
||
auto-finish countdown are configurable; changes sync back to the phone.
|
||
- **Two-way live run** — prop your iPhone up during an Apple Watch workout and it runs
|
||
the same Ready → work/rest → Finish flow with live timers, in step with the watch. It's
|
||
bidirectional: drive from either device — swipe ahead, finish a set, add one — and the
|
||
other follows. Only *human* transitions are sent; automatic ones (a rest timer ending)
|
||
advance both devices independently off shared start times, so they never fight.
|
||
- **Watch face complication** — a launcher complication you can place on any Apple
|
||
Watch face; tap it to open the app. Available in the circular, corner, inline, and
|
||
rectangular accessory slots.
|
||
- **Apple Health & Activity rings** — completed workouts are saved to Apple Health
|
||
and credit your Move and Exercise rings: recorded live on the Apple Watch (heart
|
||
rate + active energy), or estimated on the iPhone when you train without your
|
||
watch. See live heart rate and calories on the watch, and a post-workout summary
|
||
(duration, calories, avg/max heart rate, heart-rate zones, total volume) you can
|
||
revisit on any past workout. Weights display in your choice of pounds or kilograms.
|
||
- **iCloud Drive sync** — your data lives as human-readable JSON in your iCloud
|
||
Drive, synced across devices and visible in the Files app. iCloud is required.
|
||
|
||
## Architecture
|
||
|
||
iCloud Drive JSON documents are the **sole source of truth**; a local SwiftData
|
||
store is a rebuildable read-through cache populated exclusively by an
|
||
`NSMetadataQuery` observer (one-way flow: files → observer → cache). The phone is
|
||
the only device that touches iCloud Drive; the Apple Watch is a thin remote that
|
||
round-trips workout changes through the phone via WatchConnectivity.
|
||
|
||
See `REQUIREMENTS.md` for the data model and `CLAUDE.md` for project guidance.
|
||
|
||
## Building
|
||
|
||
The Xcode project is generated with [XcodeGen](https://github.com/yonaskolb/XcodeGen):
|
||
|
||
```sh
|
||
xcodegen generate
|
||
open Workouts.xcodeproj
|
||
```
|
||
|
||
Requires Xcode 26 (iOS 26 / watchOS 26, Swift 6).
