What you need
Aufbau is a native macOS application. It runs fully on your Mac — no account, no internet connection, and no additional hardware. It’s available now on the Mac App Store.
Getting started
Where to begin
Open the periodic table, pick a tool from the menu — the Reaction Lab, the Nuclear reactor, or the Design planner — and start from one of the built-in scenarios. Every result is computed from the engine's own physics, so you can change an input and watch the outcome change with it.
User’s Guide
Everything in one place
A complete walkthrough of every tool — the Chemistry Workbench, the Reaction Lab, 3-D structures, IR and NMR spectra, orbitals and qubits, the nuclear module, and more.

Your data stays yours
The app collects nothing, sends nothing off your device, and makes no network connections. Anything you build stays on your Mac.

Tell us what to build next
Aufbau is actively developed. If there's a molecule, a reaction class, or a nuclear process you'd like the engine to compute, we want to hear it.
