One file, signed and notarised by Apple. Everything it needs travels inside it: nothing else to install.

Requirements · macOS 12 Monterey or later, Apple Silicon. Nothing else to install: everything ships inside the app.

The next build is being prepared. It appears here as soon as Apple has notarised it, usually within the hour.

The trial is the whole application. Measured values and XML export are what a licence unlocks; everything else works before you pay a cent.

Opening it the first time

Open the disk image and drag Synchromatic into your Applications folder.
Double click it. macOS checks the Apple signature, which takes a few seconds the first time.
Drop in your rushes. Nothing is uploaded and no account is created.
