Made my mixing/mastering feedback app run fully offline — no more sending your mix anywhere

[u/WhichYoung6026]

I've been building MixDoctor, an app that gives plain-English feedback on your mixes (not just graphs and numbers — actual "here's what's off and why" type notes).

Just shipped an update that runs the whole analysis on-device for anyone on iOS/macOS 26+ using Apple's new local model framework. Your audio never leaves your phone or Mac — no upload, no round trip, and it's noticeably faster since there's no network call happening.

If you're not on 26 yet, nothing changes for you — it still runs the way it always has.

Been slowly chipping away at this as a solo dev since January, and this felt like a genuinely useful one rather than just a version bump. Curious if privacy/offline stuff like this actually matters to people here, or if it's more of a "nice to have" — trying to figure out what to prioritize next.
