Recording is broken
So we fixed it.
Turn your band's phones into a multi-track recording studio. No gear. No setup. Just hit record.
Multi-track iPhone recording studio for bands
PolyMic is a free iOS app for iPhone that turns multiple phones into a synchronized multi-track recording studio for bands, rehearsals, and jam sessions. Record a separate track per instrument — drums, guitar, bass, vocals — and mix them on-device. No audio interface, no DAW, no laptop required.
iOS only · Free while in early access.
Every voice. Every string. Every hit.
Captured clean, mixed instantly,
ready to share before the amps cool down.
Hear the difference
Every instrument, crystal clear
Each phone captures its own track. Play, mute, and solo to hear what multi-device recording sounds like.
Recorded with PolyMic — raw tracks, no EQ, compression, or mastering applied.
How It Works
Three steps. Zero gear.
If your band has iPhones, you already have everything you need.
Place your phones
Each band member sets their iPhone near their instrument — drums, guitar, vocals, keys.
Hit record
One tap starts synchronized recording across all devices. No setup, no countdown.
Mix & share
PolyMic auto-aligns every track. Adjust levels, balance instruments, and export — all from your phone.
Multi-Track Capture
Every instrument, crystal clear
Place a phone near each instrument. Each one captures a separate track you can mix independently — boost the vocals, tame the drums, find the perfect balance. Studio-level control from a rehearsal room.
Auto Sync
Perfectly in sync, zero effort
All tracks aligned to the millisecond automatically. No DAW, no post-production, no manual editing. Press record and everything just works.
Built-In Mixing
Mix on the ride home
Adjust levels, pan instruments, and export a polished mix — all from your phone. No laptop required. Your rehearsal recording sounds like a demo before you even get home.
Collaborate
Your band's shared studio
Everyone gets the recording. Leave comments on specific sections, suggest edits, flag the best takes. Work on your music together, even when you're apart.

FAQ
Frequently asked questions
What musicians, bands, and producers most often ask about PolyMic.
Yes. PolyMic uses two or more iPhones together to produce per-instrument multi-track recordings. Each phone captures a separate track from whichever instrument it sits next to, and PolyMic auto-aligns the tracks to the millisecond. You don't need an audio interface, mixer, or laptop.
GarageBand and Voice Memos record audio on a single device, which means one mic in the room captures every instrument together — drums usually drown out everything else. PolyMic distributes recording across multiple iPhones in parallel, so each instrument gets its own clean track that you can mix independently afterward.
For per-instrument separation across multiple devices, PolyMic is purpose-built for this exact case. Single-device alternatives like GarageBand, Voice Memos, or Dolby On cannot produce isolated per-instrument tracks no matter how good the phone microphone is — the physics of one mic in a loud room limit them.
PolyMic syncs 8 or more iPhones simultaneously. In practice most bands use 3 to 6 phones (one per instrument plus a room mic).
No. The full pipeline — recording, sync, mixing, export — runs on the iPhones themselves. There is zero extra gear to buy or carry.
Each phone records its track locally — there's no live sync stream to break during the session, so network hiccups can't drop frames. Once recording stops and the phones exchange files, PolyMic aligns every track to the millisecond automatically, with no manual alignment step in a DAW.
Yes. PolyMic is free during the TestFlight early-access period. There's no credit card and no commitment.
No. PolyMic is iOS only today. Every band member who wants to record needs an iPhone with TestFlight installed.
Yes. Multi-track export is a core feature, so you can mix on-device or take the stems into any DAW for further production.
Place one iPhone running PolyMic next to each instrument — drums, guitar, bass, vocals. Tap record on any phone. PolyMic synchronizes recording across every connected phone and gives you isolated per-instrument tracks at the end of the session, ready to mix on the phone.
