Updates are released regularly to improve functionality and add new features. ## Version history (last 5 releases) ### 1.13.4 — 2026-10-04 Easier to run your week, and more control over online booking: - Block off time: add a personal event with no time to block a whole day, set how long it lasts, or choose a last day for multi-day events. Your online booking page won't offer those times. - Multi-day jobs and events now show on every day they cover, marked "day 2 of 3." - Minimum notice for online booking: choose how far ahead clients must book (Settings under Self-scheduling). - Choose your map app for directions — Google Maps, Apple Maps or Waze (Settings under Travel & mileage). - Merge duplicate clients: Find duplicates now groups the same name or phone number, and "Keep this one" combines them. - Returning clients are recognized when booking online, however they type their phone number. - The invoice screen fits your phone better, and date fields line up properly. - Clearer labels for VoiceOver users. - Bug fixes and reliability improvements. ### 1.13.3 — 2026-10-03 - Invoice PDFs now show your logo, your thank-you line and your small mark — including Print / Save PDF in the iPhone app and the PDF attached to emailed invoices. Void invoices are marked VOID. - Import pianos is back as its own button on the Clients and Pianos pages, so you can bring in your pianos from Gazelle or a spreadsheet at any time. Each piano is matched to a client already in Cantus. - Add your bank transfer / EFT details in Settings under Business profile, and they appear on invoices that are still owed. - A client’s invoices now show on their own client page ### 1.13.2 — 2026-09-30 Fixed and improved: - "Print / Save PDF" on an invoice now works properly — tap it to save or share a real PDF, right from your phone - Invoices and receipts emailed to clients now include a PDF attachment - Added a spot for your bank transfer / EFT details on invoices, for clients who pay that way - Fixed a bug where a saved invoice didn't show up right away on the client's page - Accessibility fixes in the invoice editor for screen reader users ### 1.13.1 — 2026-09-28 Fixing critical bug in packaging ### 1.13.0 — 2026-09-27 Itemized invoices and sales tax - Build invoices from your services, with quantities, a discount, payment terms and a note to your client. Invoices made from a completed appointment fill in its services for you. - Collect sales tax (or VAT/GST) if you need to: set it up in Settings → Business profile, choose which services are taxable, and see how much tax you've collected in Money. If you don't collect tax, nothing changes. - Mark invoices paid by cash, check, card or bank transfer. Every payment is counted in Money exactly once, and paid invoices are locked. - Void an invoice to correct a mistake. It stays in your records and no longer counts as owed. - Printing and PDFs now show just the invoice. - Clearer messages when something goes wrong, a better Stripe setup status, and several smaller fixes. - Reliable offline use: Cantus now opens and works properly with no connection, and it can store much larger client lists on your device for offline access. - Import from any spreadsheet: bring in clients and pianos from CSV or Excel files exported by any system, not only Gazelle. You choose which column matches which field before importing. - Faster client list: large client lists scroll and search more smoothly. - Your branding on invoices: invoices now show your uploaded logo, or your business name if you haven't uploaded one. - Invoice fixes: reprinting or re-sharing an invoice no longer changes its paid status, card fee rate or invoice numbering. - Accessibility: screen readers now move correctly into the invoice and appointment windows when they open. - Self-scheduler improvements: clients can add a piano serial number and go back to earlier steps, prices show in your currency, and the services clients select are now recorded correctly. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
