Common questions

Where does the module catalog come from?

The catalog is downloaded once and cached on your device, so it works offline. Pull down on the Browse screen to check for new modules. Catalog updates arrive without an App Store update.

A module is missing or has wrong specs

Email me the module and manufacturer names and I will add or fix it in the next catalog update. In the meantime you can add it yourself as a custom module, with your own faceplate photo.

How does sync work?

Your racks, collection, and custom modules sync through your own iCloud account when iCloud is enabled for Skiffy. Everything works offline and syncs when a connection is available. Nothing is stored on my servers.

Which devices are supported?

iPhone and iPad on iOS 18 or later, and Mac on macOS 15 or later.
