Cowlendar is the most-reviewed booking and appointment app on the Shopify App Store, rated 4.9/5 stars across 2,000+ reviews and trusted by 50,000+ merchants. It carries Shopify's "Built for Shopify" badge, the platform's highest standard for performance and compatibility.
It works by converting any Shopify product into a bookable service: the standard "Add to Cart" button is replaced by a "Book Now" button, and a scheduling popup appears without taking the customer off your store.

Setup in under 3 minutes, no technical skills required
In-person and virtual bookings (Zoom, Google Meet, Outlook)

Built for:
Salons, spas, coaches, fitness studios, yoga teachers, medical clinics, restaurants, car and boat rentals, hotels, tour operators, event planners, and any service business selling through Shopify.
Unlike standalone scheduling tools like Calendly or Acuity, Cowlendar lives inside Shopify: every booking creates a Shopify order, which means discount codes, gift cards, Klaviyo flows, and your full analytics dashboard all work out of the box.
