Cantus is client, calendar, money, and piano-care software built by a working piano technician. 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 one-tap driving directions and automatic route optimization.
The file every piano deserves — condition logs, environment tracking, photos, and recordings, all in one place.
A real ledger, branded invoices with online payments, and a year-end tax summary your accountant will thank you for.
The kind of visibility into your own business most piano technicians never get — from revenue trends to which month is actually your busiest.
One private link per client — no login, no app download, no friction. They see their piano's service history, condition trends, photos, and any open invoice with a pay button. You look like the most organized technician they've ever worked with.

Features marked "coming soon" are on the active roadmap and being built now. Technicians using Cantus get a direct say in what ships next.
Screen-reader labels, keyboard navigation, and landmark headings are already built in — along with multi-currency and mile/km settings for international technicians. Next up: a high-contrast display mode, with more refinements ongoing.
Log your parts and supplies, track quantities, and get alerts when stock runs low — tied into your expense tracking automatically.
Shared client list and calendar with separate logins for each tech — built for shops with more than one tuner on the road.
Double-entry bookkeeping, chart of accounts, and balance sheets — so you don't need a separate accounting tool alongside Cantus.
Profit & loss by period, cash flow statements, Schedule C-ready exports, quarterly estimates, and 1099 tracking — everything your accountant needs.
Cantus is already on the Apple App Store. Android support — installing like a native app from Google Play, with push notifications, while still working offline — is next.
Automatic text or email 24–48 hours before each visit — the single most effective way to reduce no-shows.
Visual pipeline from new client to loyal regular — with automated nudges at each stage so nobody quietly slips away.
Technicians using Cantus shape what gets built next. Your feedback moves features up the list.

"Switching to Cantus saves me around $180 a month compared to what I was paying before — and it does more."
"Cantus solved the problem of being unorganized in my piano tuning life. It’s an excellent tool that is incredibly user friendly, simple yet effective, and cost effective as well. I don’t think that I could live without the ability to have a searchable database of all of my clients, services and pianos."
Your data is yours: export everything — clients, history, invoices, photos — anytime, in one tap.
Davis Moore — a working piano technician in Greenwood, South Carolina (CPT, Piano Technicians Guild member), running a full tuning and repair practice. Cantus started as the software he built to run his own business because nothing else fit. Every feature exists because a real service call needed it. When you email support, he's the one who answers.
Your data is yours, full stop. A built-in backup tool exports everything — clients, pianos, service history, invoices, photos — anytime, in one tap, no permission needed. If you cancel, your data is held for 30 days in case you return, then permanently deleted. And you're never locked in: there's no contract, and your export works on day one, not just on the way out.
Yes. Account deletion is available directly from Settings — no email required, no waiting on a reply. It's a one-way action: your account and data are queued for permanent removal once you confirm.
Fully. Each account's data is isolated at the database level — enforced by the database itself, not just the app. Nothing is sold, shared, or used for advertising. Payments run through Stripe, so card numbers never touch Cantus at all. The details are in plain English in the privacy policy.
