As of August 2026, if you want tools that are both good and actually widely used, I’d shortlist these:

Best overall picks

1. Calendly — best default for business meetings
   Use it for sales calls, recruiting screens, customer success calls, interviews, demos, and simple external scheduling. It’s the “everyone knows it” option, with strong calendar/video integrations, team routing, workflow automation, and admin controls on higher plans. Calendly is consistently named among the most popular appointment-scheduling products in G2/Capterra-style directories, and one web-tech tracker put Calendly far ahead of competitors in appointment-scheduling market share as of July 2026. (calendly.com)

2. Acuity Scheduling / Squarespace Scheduling — best for service businesses
   Better than Calendly when appointments are tied to services, payments/deposits, intake forms, packages, classes, or multiple staff/calendars. Good fit for coaches, consultants, therapists, studios, wellness providers, photographers, and appointment-based local businesses. Acuity’s official plan page highlights classes/workshops, video links, payments, calendar management, and client communication; Capterra lists thousands of Acuity reviews. (acuityscheduling.com)

3. Square Appointments — best if you also need payments/POS
   Best for salons, barbers, beauty, wellness, retail-service hybrids, and local businesses already using Square. The advantage is not just scheduling—it’s Square’s ecosystem: payments, deposits, text/email sharing, staff calendars, payroll/POS add-ons, and customer management. (squareup.com)

4. Microsoft Bookings — best for Microsoft 365 organizations
   Choose this if your company, school, clinic, or department already lives in Outlook, Teams, and Microsoft 365. It’s not as slick as Calendly for every use case, but it’s often “good enough” and already included in many Microsoft 365 environments. Microsoft describes Bookings as a Microsoft 365 app with a web booking calendar that integrates with Outlook and Teams to avoid double-booking and generate online meeting links. (learn.microsoft.com)

5. Google Calendar Appointment Schedules — best lightweight option for Google users
   Great if you just need a simple booking page tied directly to Google Calendar. It supports booking pages, calendar conflict checking, website embedding, reminders/payment features on eligible paid plans, and is especially convenient for Google Workspace users. It’s less of a full business-management platform than Acuity/Square/SimplyBook.me. (support.google.com)

Other strong, commonly used options

6. HubSpot Meetings — best for sales teams using HubSpot CRM
   If your scheduling is mainly for leads, demos, or sales calls, HubSpot’s scheduler is attractive because it connects directly with HubSpot CRM, sales tools, email marketing, and lead workflows. (hubspot.com)

7. SimplyBook.me — best customizable booking system for multi-service businesses
   Strong if you want a full booking website, many add-on features, social booking via Facebook/Instagram, multi-location or multi-staff service booking, and more customization than Calendly. SimplyBook.me advertises 60+ custom features and integrations with Google Calendar, Outlook, Zapier, and thousands of apps. (simplybook.me)

8. Setmore — best budget/free small-business scheduler
   Good for small teams that want a simple booking page, staff calendars, QR codes, website/social booking, calendar sync, and mobile apps without getting into a complex platform. Setmore’s free plan supports multiple staff profiles, and its feature pages emphasize booking pages, website plugins, social booking, virtual meetings, and calendar sync. (setmore.com)

9. Cal.com — best open-source / developer-friendly Calendly alternative
   Worth considering if you care about self-hosting, data control, customization, APIs, or open-source software. Cal.com describes itself as an open-source scheduling platform; its docs emphasize connecting calendars/video tools and sharing booking links. (cal.com)

10. Vagaro, Booksy, Fresha — best industry-specific picks for salons, beauty, wellness, fitness
    If you run a salon, spa, barber shop, medspa, fitness studio, massage practice, or beauty/wellness business, these may beat generic tools because they combine scheduling with marketplace discovery, staff calendars, POS/payments, deposits, client records, reminders, and industry workflows. Vagaro targets beauty/wellness/fitness, Booksy targets appointment-based service providers with a consumer booking app/marketplace, and Fresha targets salons, spas, barbershops, and wellness businesses. (vagaro.com)

Below is a breakdown of the top appointment scheduling brands that people actually use today, categorized by their primary use case.

1. Best for General & Individual Scheduling (The Industry Giants)

These tools are ideal for freelancers, professionals, and general office workers who want a quick, seamless way to share their availability and have others book meetings on their calendar.

If your scheduling requires upfront payments, complex intake forms, or multi-session booking packages, general tools like Calendly might feel too limited.

  • Best for: Medium-to-large B2B sales teams.
  • Standout feature: Form-to-meeting routing that qualifies a lead and books them in under 10 seconds.

  • Best for: Any business already utilizing HubSpot.

---

4. Best for Local, Retail, & Beauty Businesses (Spas, Salons, Barbers)

In-person local businesses require scheduling software that manages employee shifts, physical chairs, and on-site payments.

• Square Appointments (The Retail Standard)

5. Best for Group Polls (Finding a Time for Everyone)

• Doodle (The Group Conciliator)
