Sculptor

A personal muscle-map training app for iPhone, in the browser.

• Body – tap a muscle, pick a goal (Strength, Endurance, Agility, Mobility, Stretch), see the top exercises with the ones you do most at the top, and log sets. Barbell bench press has a live 3D form model with Muscles, Breath and Mind layers.
• Mind – tap the brain to run a 1, 3 or 5 minute breathing session, and practise eight mind skills (Focus, Trust, Observe, Picture, Inner voice, Feel, Calm, Habits).
• Progress – overall strength, charts per exercise and scores per muscle group.

Light and dark mode follow the phone, or set them in Settings.

Accounts

Settings has sign-up, sign-in and sign-out, backed by Supabase. Without an account everything stays in this browser's local storage, exactly as before — signing in is optional. Once signed in, sets, mind sessions and your profile sync to every device you sign in on, and the first sign-in offers to upload the sets this browser already has.

Each table has row-level security keyed to your user id, so an account only ever reads and writes its own rows. Sign-up sends a confirmation email: open the link before signing in. The schema and policies are in supabase.sql.

Run it

Open index.html in a browser, or serve the folder with any static host (GitHub Pages works). Data is saved in the browser's local storage on each device. The 3D model loads three.js from jsDelivr.

Edit it

Source lives in src/. After a change, rebuild the single page:

python3 build.py

File	What it holds
src/config.js	Supabase project URL and anon key
src/supabase.js	Small Supabase auth and REST client
src/core.js	Body map geometry, muscles, exercise library, strength standards, storage, scoring
src/ui.js	Body and Progress tabs, sheets, logging, settings, theme
src/mind.js	Mind tab, skills and drills, breathing session
src/form3d.js	3D form viewer (three.js)
src/app.css, src/form3d.css	Styles
src/icon.svg	App icon, inlined into the page as the tab favicon

The tab favicon is inlined from src/icon.svg by build.py. The home-screen icon icon-180.png is a separate raster, so regenerate it after changing the icon — drop the rx corner radius first, since iOS applies its own rounded mask:

sed 's/ rx="7.5"//' src/icon.svg > /tmp/icon-ios.svg
qlmanage -t -s 180 -o /tmp /tmp/icon-ios.svg
sips -s format png /tmp/icon-ios.svg.png --out icon-180.png

Add to the iPhone home screen

Open the GitHub Pages link in Safari, tap Share, then Add to Home Screen.
