Your whole business, one app.
Cantus is client, calendar, invoicing and piano-care software built by a working piano technician. It runs your business, and it keeps working in the basements and church halls where the signal doesn’t reach.
$47.95 a month or $479.95 a year · unlimited clients · on the App Store
Built by a piano technician, not a software company. Davis Moore runs a full tuning and repair practice in Greenwood, South Carolina, and built Cantus to run it. Every feature exists because a real service call needed it, and when you email support, he’s the one who answers.
Everything a piano business needs. Nothing it doesn’t.
