We use Fresha for our diary. We haven't enabled online bookings due to the complexity people's diaries with multiple appointment lengths but do use most of the others features. It is quite intuitive and you will be shown it onthe first day.

Your diary should be set up for your regular days.,

fresha.com has a whole host of info if super interested.
