Stackapella and ChoirMate

As of November 2026

ChoirMate runs a choir: members, set lists, calendar and attendance, messages and files, with a Track Mixer to practise your part. Stackapella helps each singer learn their part: it listens as you sing, and has choir groups and practice tracks.

ChoirMate is for

Choir directors who want rehearsals, attendance and messages in one place.
Set lists, sheet music and audio files for the whole choir.
Practising in the car with CarPlay, or on an Apple Watch.

Stackapella is for

Each singer getting feedback on their pitch while they learn.
A course that teaches singers to hold a harmony part.
Recording every part yourself, stacked in time.

Questions

Can I use both?

Yes. A choir can keep its rosters and files in ChoirMate and practise parts in Stackapella.

Does Stackapella have choir tools?

Choir groups and practice tracks, so a director can share songs and each singer can learn their part. It doesn't do attendance, calendars or messages.

Is Stackapella free?

Yes: every course and every song in the library, with a free account, and unlimited workouts, your history, singing with friends and choir groups. Plus, for $4.99 a month or $39.99 a year, adds more storage, MP3 and stems, and unlimited private arrangements.
