side-by-side breakdown

Choir vs AmpMe vs SoundSeeder

The 5 main options in phone audio sync — Choir, AmpMe, SoundSeeder, Bose Connect, Apple Audio Sharing — side by side on 7 criteria that actually matter. No padding, just which one wins which scenario.

Why this comparison exists

People trying to turn their iPhones into a speaker array usually start with AmpMe (first Google result), then check SoundSeeder (cross-platform claim), then wonder "doesn't Apple already do this?"

Short answer: each does part of it, none does all of it. This table shows which one wins which scenario.

Data: App Store ratings (May 2026), user reviews, our own measurements. Updated quarterly.

Choir, AmpMe,
SoundSeeder
and the rest.

Most categories are trade-offs. AmpMe supports more platforms but doesn't keep its sync promise (200ms+ typical). SoundSeeder honestly plays local files but iOS is weak. Bose is locked to its speakers. Choir deliberately stays iPhone-only: niche but keeps its word.

Who Choir is NOT for: Android owners, Spotify-centric users, anyone wanting many more devices (10+). For that, Sonos or a brand ecosystem makes more sense.

Full comparison + verdict for each competitor

Which one when?

Choir wins →

You have 2–32 iPhones lying around and want to play your own music without buying a subscription.

AmpMe →

You already have Spotify Premium and sync precision is not critical. You also have Android friends.

SoundSeeder →

You only play local mp3s and you're on Android. Skip it on iOS.

Bose Connect →

You already own Bose speakers. Best for stereo-pairing two of them.

Apple Audio Sharing →

You're sharing one source across 2 AirPods. Not a speaker scenario.

Verdict:

Compare,
then try.

Choir is free for 30 days. No account, no card required.
