Your week at a glance, and clients book themselves.
A calendar built around how piano technicians actually work: tunings, multi-piano jobs, days on the road, and time off. Share a booking link, and clients pick an open time that already fits your schedule.

Every appointment, every day off, in one place.
Month and agenda views show client appointments, booking requests and your own personal events together. Tap any day to see everything on it, and add an appointment from the agenda in one tap.
- Month and agenda views, color-coded by status
- Multi-day jobs and events show on every day they cover
- Repeating appointments: weekly, every two weeks or monthly
- Personal events to block off time, a few hours or several days
- Booking requests you confirm or decline in one tap

A booking page clients actually use.
Share one link on your website, your Google Business Profile or in your reminder emails. Clients choose their piano and services, see only times you’re really free, and send a request you approve, or one that’s confirmed automatically if you prefer.
- Only shows times that fit around your appointments and time off
- Minimum notice, such as 24 hours, and how far ahead clients can book
- Suggests days you’re already in the client’s area
- Recognizes returning clients and fills in their details
- Email confirmations to you and your client
- Coming October 21: address suggestions as clients type, a service area, and returning clients choosing their pianos
