About

Bookaster is appointment-scheduling and CRM software for local service businesses - hair and beauty salons, barbershops, dental and medical clinics, gyms, studios and restaurants. Each business gets a branded booking page where clients self-schedule 24/7, a staff calendar with per-employee availability and multi-location support, and a client database with full visit history. What sets it apart is WhatsApp: confirmations, reminders and post-visit review requests are sent automatically from the business's own WhatsApp number, which is what reduces no-shows. Clients can reply to confirm, reschedule or cancel, and the calendar updates itself. It also covers invoicing and receipts, expense tracking, revenue reports, staff commissions, prepaid packages, walk-in queues and marketing campaigns. Runs in any browser and installs as an app on phones and tablets. Available in 7 languages including Arabic (right-to-left). Free 90-day trial, no card required.

Pros & Cons from Real Users

Pros

  • It’s very simple to use and seamlessly manages your calendar. Removes the manual to and fro for scheduling.
  • Completely free with no feature limits - Unlike competitors like Calendly that restrict free users to one event type, cal.id offers unlimited scheduling with all features available at no cost Cal, which is particularly valuable for freelancers, creators, and solopreneurs. Built-in payment processing - The platform allows you to accept payments directly for meetings and appointments within the scheduling system, eliminating the need for separate payment solutions. Extensive integrations and white-label options - Cal.id connects with popular tools like Salesforce, Slack, and Zoom, and offers white-label embedding on your own domain with ISO, GDPR, and CCPA compliance included
  • Love this using and it's great for call booking and i can see the analytics as well. Thanks team to make it so great
  • Been using it for a while and can say this is fast and easy to setup and also have all the features that I require to start my therapy sessions.
  • Cal ID makes scheduling straightforward and practical. The setup is quick, the booking pages look clean, and calendar syncing works well for day-to-day use. I especially like that the core features are genuinely free, including multiple event types and team scheduling, which is rare compared to similar tools. It eliminates back-and-forth emails and works well for client calls, internal meetings, and basic team coordination without unnecessary complexity. and quick support over chat with live meeting also

Cons

  • So far, didn’t find anything which I didn’t like.
  • Newer, less established platform - As a relatively new entrant competing against established players like Calendly, it may have a smaller user base and potentially fewer third-party integrations or community resources available. Limited track record - Being a newer service means there's less long-term data on reliability, ongoing development, and whether the free model is sustainable, which could raise questions about future pricing or feature changes. Potential feature maturity - While it offers many features, some advanced capabilities or refinements that come with more mature platforms may still be in development or less polished compared to competitors that have had years to optimize their user experience.
  • it's too great, when you use it you will fall in love with it. so if you wanna fall in love with its feature go man and use it. Thanks team to make it so great
  • As of now nothing, as they are new and adding so many features speedily
  • Some advanced customization options and deeper workflow automation are limited compared to more mature enterprise tools. A few settings take time to discover, and documentation could be clearer for first-time users who want to fine-tune rules or integrations.
