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.

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.
Which one when?
You have 2–32 iPhones lying around and want to play your own music without buying a subscription.
You already have Spotify Premium and sync precision is not critical. You also have Android friends.
You only play local mp3s and you're on Android. Skip it on iOS.
You already own Bose speakers. Best for stereo-pairing two of them.
You're sharing one source across 2 AirPods. Not a speaker scenario.
