Zewa

About project

ZeWa is a mobile appointment and waitlist management platform created for service businesses and their customers.

Customers can discover nearby providers, view live waiting information, join a queue, schedule appointments, and receive timely notifications.

Businesses can manage staff, services, schedules, bookings, and customer flow from a dedicated application, reducing manual coordination and improving the service experience.

Review

Zewa came to us with a vision to simplify appointment and waitlist management for both businesses and customers. The platform was designed to make service booking faster, more transparent, and more convenient through real-time wait times, instant notifications, easy check-ins, and scheduled appointments. We were glad to partner with the Zewa team and help transform their idea into a scalable digital solution that improves customer experience and gives businesses greater control over daily operations.
