Cantus is client, calendar, money, and piano-care software built by a working piano technician — not a generic CRM squeezed to fit. It runs your whole business, and it runs offline in the basements and church halls where the signal doesn't reach.
Every client, every piano, every visit — with a recall queue that knows who's overdue before they do.
Your whole week at a glance, with directions and history one tap from any appointment.
A real ledger, branded invoices, mileage, and a net-worth view of the business you're building.
Condition logs, humidity & pitch trends, photos, and recordings — the file every piano deserves.
No fields to hide, no features that don't apply. Every screen assumes you already know what a Dampp-Chaser is.
Log a visit in a basement with no bars. Cantus syncs the moment you're back online — nothing lost, nothing blocked.
No client-count ladder that punishes you for growing. Unlimited clients, always, for one simple monthly rate.

We'd rather tell you where Cantus is still catching up than pretend it does everything. The rows above marked "coming soon" are being built now — beta technicians get a say in how.
Beta seats are limited and personally reviewed — no open signup.
Your business name, logo, and invoice details — ready in minutes.
Import a spreadsheet you already have, or add them as you go.
Install it like an app on your phone, and start logging your next visit.
Cantus is opening to a small group of piano technicians before its public launch. Tell us a bit about your business, and we'll send an invite.
