Audire

I am the developer of Audire. Audire is a MIDI player built for choir and a cappella part practice on iPhone, iPad and Android. Import the MIDI files your choir already shares and Audire auto-assigns voice parts (including divisi and two-choir layouts). Practice with a per-part mixer (mute/solo/level), A–B loop, tempo control, transpose and shareable playlists. All practice features are free; a one-time purchase unlocks an unlimited library. No subscription, no account, no tracking.
