Payment firm Square has introduced a new service and iOS-only app, both called Appointments, that is aimed at businesses that rely on client bookings, such as (for example) a cleaning service or landscaping firm. The iOS app is free, but the service costs $30 per month for one user, $50 per month for two- to five-person teams, and $90 a month for unlimited employees or owners. For those who use Square Register to accept credit-card payments, the service connects to that automatically.
