## What is PhiStruct?

PhiStruct is a touch-first ball-and-strut geometry builder: you don't just
view finished shapes — you construct them.

Tap a connector ball, tap a glowing hole, and place a strut. Keep going until
you've assembled Platonic solids, Archimedean solids, golden-ratio forms, and
more. Struts are never allowed to pass through each other, so every model is
physically buildable on your desk.

WHY IT'S DIFFERENT
• Hands-on construction, hole by hole — like a strut kit in your pocket
• Collision-proof builds: if it builds in the app, it builds in real life
• Exact φ (golden ratio) math — zero drift
• Fully offline. No account. No ads. No subscription.

WHAT YOU CAN DO
• Free build — pick color and length, tap holes, invent your own models
• Guided builds — step through 134 curated polyhedra (flat shapes, prisms,
  Platonic and Archimedean solids, quasicrystal geometry) with the next hole
  highlighted, or complete instantly
• Reference ghost — a translucent target to build alongside freehand
• Parts list — color × length × count for sorting or buying real struts
• Export PNG, full-color GLB (Blender / AR / web), or centered STL for 3D
  printing
• Save and reopen exact project files, including .vZome from desktop vZome

WHO IT'S FOR
• Makers and 3D-printing hobbyists who want to verify a build before printing
• Math teachers preparing a polyhedra lesson — walk through it step by step
• Geometry lovers who want to make something, not just look at it

One-time purchase. Your projects stay on your device unless you export them.


## Version history (last 3 releases)

### 1.2 — 2026-09-04

Place any build on a real table in AR.

• Walk around a kit at real size
• Tap glowing holes on the table to keep building
• Leave AR with the cube control; the kit stays on the desk

### 1.1 — 2026-08-22

A bigger library, a quieter first minute, and models that stay sharp.

• 134 guided builds — Easy first, Hard when you want it
• First launch opens Library so you start with Triangle, not a floating peg
• Chrome stays out of the way; the kit keeps the colour
• Large models stay sharp while you orbit
• Guided camera frames the next hole

### 1.0 — 2026-08-04

No release notes.
