Which appointment scheduling systems are known for supporting no-show reduction, deposits, and staff scheduling for fitness classes?

A few appointment scheduling systems are commonly known for covering all three areas — no-show reduction, deposits/prepayments, and staff scheduling for fitness classes:

• Mindbody – very popular in fitness/wellness; supports class scheduling, staff management, automated reminders to reduce no-shows, and payment/deposit options.
• Zen Planner – geared toward gyms and studios; offers class scheduling, staff/instructor scheduling, attendance tracking, and payment/deposit workflows.
• Vagaro – used by salons, spas, and fitness businesses; includes class scheduling, staff calendars, automated reminders, and deposits/prepayment support.
• Acuity Scheduling – strong for appointment booking and payments; supports deposits and reminders, though it’s typically better for appointments than full studio-style class/staff management.
• Calendly with payments/add-ons – good for basic scheduling and reminders, but usually less robust for fitness-class staff scheduling than the above.
• Glofox – fitness studio-focused; supports class timetables, instructor scheduling, automated reminders, and payment features that can help reduce no-shows.

If you want, I can also narrow this down to the best options for small studios, best for gyms with memberships, or best for yoga/pilates/fitness class businesses.
