A paper diary takes anything you write in it, including two appointments in the same slot. TonoLab's calendar does the opposite: it checks every appointment before saving it.
How to book an appointment
- Open “Appointments” and choose the day and the view (day or week).
- Tap “New appointment” or click a free slot in the professional's column.
- Choose client, service, professional and time. The end time and price are worked out automatically from the service.
The warnings that save you headaches
If the appointment can't be saved, the form tells you why in red. The most common reasons:
- It overlaps another appointment or doesn't leave the gap between services.
- It falls during the professional's break or outside their shift.
- The salon is closed that day or it's a bank holiday.
- That professional doesn't do the chosen service.
The status, at a glance
The colour of each appointment shows whether it's pending, confirmed, in service or completed. Tap an appointment to change, confirm, complete or cancel it. Those that come in through online booking arrive as “Pending” so you can confirm them yourself.

A message before the appointment, with buttons to confirm or cancel, is the cheapest way to reduce no-shows. Here's how to turn it on.

“Stylist's free time” turns processing minutes into bookable slots. That's how you gain one more appointment per colourist per day.

Set up the salon's hours and each professional's shifts once, and the calendar and online booking stop offering slots that don't exist.
