Music library management for macOS

Built for how producers actually work.

Metrimus reads your library as it is — BPM, key, and version relationships surface automatically, without forcing your files into someone else's folder structure.

What it does

Organization that assists — it doesn't take over.

01

Automatic detection

BPM, key, and energy are analyzed the moment a track is imported — entirely offline, on your Mac, using Apple's own audio frameworks. Nothing uploaded, nothing to wait on.

02

Version grouping

Filenames like _v2, final, and bounce are recognized automatically, so takes and stems land under one track instead of scattered across folders.

03

Cluster suggestions

Metrimus proposes groupings by tempo, key compatibility, similar names, or projects that have stalled. Accept the ones that fit — ignore the rest.

04

Pattern surfacing

Completion rates, tempo and key distributions, and stalled-project notes — drawn from your own library, not pushed at you as a dashboard.

05

Fast search & filtering

Search by name, tag, or genre, or filter by status and tag combinations at once. Filters compose and hold as you narrow things down.

06

Your files stay yours

No cloud sync, no proprietary library format, no account required. Metadata and tags can be exported and re-imported anytime.

Inside the app

What it looks like once your library's actually in there.
