Boost Calendar is an online booking system for coaches, trainers, and studios in the sports, fitness, and health sectors. Developed from more than 20 years of boutique studio experience, the platform helps appointment-based businesses manage bookings, schedules, and clients in one place. It serves a range of professionals, including personal trainers, Pilates and yoga studios, wellness providers, therapists, and beauty salons.

Customers can book and pay online, while businesses can manage appointments, group classes, courses, workshops, programs, and package deals such as multi-visit cards. Features include a central calendar, automated email reminders and follow-ups, customer management, and options to connect booking pages to a business website. Payments can be taken online through Mollie or Stripe, or in person. Boost Calendar also integrates with tools such as Google, Outlook, and Apple calendars, Zoom, and Mailchimp, and supports multiple languages and currencies. The service aims to reduce administrative work, missed appointments, and back-and-forth messaging. Prospective customers can schedule a free demonstration and then try the platform free for 14 days.
