HarmonIQ Music Player

Music for your own collection — finally on iPhone.

HarmonIQ plays the MP3s, FLACs, and ALAC rips you already own — straight off your drive. Built for the people who never threw out their music folders: the CD ripper with three external drives, the Napster-era curator with a meticulous "Best Of 2003" directory, the audio-archivist who treats a hard drive like a library.

Drive-portable by design. Plug a USB-C SSD into your iPhone, point HarmonIQ at the folder, and your collection appears. The on-drive index lives next to the music — move the drive, the library moves with it. No account. No subscription. No re-indexing on a new device.

100% offline. No network at index time, playback time, or AI curation time. Plug in on the plane, in the subway, in the woods. It plays.

WHAT'S INSIDE

• Real 10-band equalizer. AVAudioEngine + AVAudioUnitEQ — the sliders move the actual signal. Presets (Flat, Rock, Pop, Jazz, Classical, Bass Boost, Vocal Boost) plus persisted custom curves.

• 17 Smart Play modes. Pure Random, Artist Roulette, Genre Journey, Album Walk, Decade Shuffle, Mood Arc, Deep Cut, Era Walk, Genre Tunnel, plus AI-curated Vibe Match, Storyteller, and Sonic Contrast.

• On-device AI by default. AI Smart Play prefers Apple Intelligence's foundation model on iOS 26 + iPhone 15 Pro and newer. Optionally bring your own Anthropic API key for cloud fallback. Your library never leaves your phone.

• Browse by language, artist, album, decade, or folder. New in v1.1: a Language hub partitions your collection into Chinese, English, and Other.

• Real artist headshots. Opt-in fetcher pulls photos from MusicBrainz, Wikidata, TheAudioDB, and Wikipedia. Tiles always show a real headshot or a placeholder — never an album cover standing in.

• Classic skin support. Drop in classic .wsz skin files; 9 bundled. Skinned main window, equalizer, and playlist all render from the original sprites.

• 16 visualizer styles. Spectrum, oscilloscope, plasma, mirror, radial pulse, particles, fire, starfield, plus 8 fancy oscilloscope variants. Tap to cycle.

• Background playback with full lock-screen, Control Center, Live Activity, and Dynamic Island controls.

• Sleep timer. Auto-stop after 15/30/45/60 minutes or at the end of the current track, with a live LCD countdown.

WHY IT EXISTS

Streaming services can pull a license tomorrow. Recommendation engines optimize for engagement, not for you. HarmonIQ is a different deal: you own your files, you own your playlist algorithm, you own your taste. No analytics, no tracking, no recommendation graph shipped off for ad targeting.

Your collection deserves a real player.
