Skiffy

Skiffy is a simple, focused Eurorack case designer for iPhone, iPad, and Mac. Browse modules, build a collection, and lay out your rack to scale. BROWSE • A large, growing catalog spanning many manufacturers, with real faceplate art and specs, cached for offline use • Search that ignores accents and word order; filter by function (VCO, VCF, VCA, LFO, sequencer, effect, and more) and by 3U or 1U format; sort by name, manufacturer, or HP COLLECTION • Track the modules you own and the ones on your wishlist, and pick your preferred faceplate variant • Add custom modules with your own faceplate photo and a crop-to-fit editor RACKS • Multi-row cases with a typed HP width and the 3U and 1U rows you choose • A to-scale canvas on a single HP grid, so 1U and 3U rows line up exactly. Pinch or scroll-wheel to zoom, pan, and fit to screen • Drag a module into a slot, rearrange by dropping it beside others (neighbours slide aside), or set it aside outside the case, with snapping and haptics • A searchable module picker that only offers modules that fit the tapped slot • Live metrics: HP used, +12V / −12V / +5V draw against your budget, module count, total value, and maximum depth, plus a full stats sheet EVERYWHERE • One app for iPhone, iPad, and Mac, with native macOS forms and keyboard and trackpad support • Your racks, collection, and custom modules sync through your own iCloud account, and everything works offline • Free, with no account, no ads, and no tracking. The catalog is anonymous and your data stays in your iCloud
