The best appointment schedulers and booking apps in 2024

What do a beauty salon, medical practitioner, and consulting agency have in common? They all need an easy and reliable way to schedule client appointments without wasting time or double-booking staff. No matter your industry, your service-based business can benefit from a quality appointment scheduling app.

The best appointment scheduling software simplifies the booking process on both ends. Thanks to your custom booking page, clients can schedule and pay for appointments on their own—while new bookings automatically appear on your calendar, keeping you and your team organized. And the very best appointment schedulers offer additional features like embeddable widgets for your website, routing forms, and custom email and SMS reminders.

For this article, I tested dozens of appointment scheduling apps looking for feature-rich, reliable tools that balance customizability and ease of use both for you and your customers. I narrowed it down to the top five booking apps, to help you decide which online appointment scheduling tool is right for your business's unique needs.

The best appointment scheduling and booking software

• Acuity Scheduling for ease of use

• Setmore for free booking software

• Square Appointments for the best mobile booking app with built-in POS

• SimplyBook.me for international businesses

• Book Like A Boss for booking and website building

What is an appointment scheduler?

Appointment schedulers are business tools that allow clients to book, reschedule, and cancel appointments through a web interface. When clients want to make an appointment, they go to your business's website, Facebook Page, or anywhere else the booking software is supported, and choose an available date and time.

On the backend, you enter parameters about when people can book certain services, based on business hours you set, as well as the times and dates that your staff or other resources are available. The app also prevents double-booking and over-booking, and gives you the flexibility to block off times when certain services may be unavailable.

Say you run a pet grooming business and your poodle cutting specialist takes a two-week vacation. You can enter her days off in the appointment scheduling app ahead of time so that your clients won't be able to book any poodle grooming time during the days that she's gone.

What makes a great appointment or booking app?

The best booking apps do more than simply give clients a list of available times when they can come in for a meeting, treatment, or service. They also let your clientele cancel and reschedule appointments without having to contact you. Additionally, they make it easy for business owners and managers to do their jobs, allowing you to streamline communication, centralize payments, and manage your staff. Here's what you should expect from the very best appointment scheduling apps:

• Flexibility. The best appointment scheduling apps know that different kinds of organizations have different needs, so they let you deeply customize how your bookings work. A small gym offering one-on-one training sessions should have a different booking experience than a community workshop that rents gardening equipment. Do you want your clients to be able to choose from a menu of services? Should they be able to specify the location for their appointment, such as for services offered at their home? Though there are some great niche options out there (like Vagaro for salon, spa, and fitness businesses), the best appointment scheduling apps let you customize these aspects.

• Calendar syncing. Nearly all appointment scheduling apps let you sync with a calendar. Some even require it. That way, you can see your business's scheduled appointments alongside other important information, such as when you'll be closed for holidays or renovations. Plus, the app can cross-reference your availability with the events on your primary calendar. For our tests, apps were only considered if they offered syncing with at least one popular calendar—and priority was given to apps that offered two-way syncing.

• Payment processing. The best appointment scheduling apps let you collect a payment at the time of booking. That way, you can take a deposit for an appointment or have clients pay for their services upfront. If a client doesn't show up, your business isn't at a total loss.

• Integration with third-party tools. Your appointment scheduling tool absolutely needs the ability to connect to the rest of your tech stack. If the app can't integrate with tools like Slack, Mailchimp, and Zoom (or at least let you set up your own connections with Zapier), it has no business being on this list.

• Value. Ideally, an appointment scheduler should be accessible to solopreneurs and enterprise teams—and everyone in between. The best tools offer a free plan as well as a selection of paid plans that provide a good value for the cost.

• Professional presentation. Your appointment scheduler should be an extension of your brand. The appointment scheduling process should be streamlined, glitch-free, and aesthetically pleasing. It should also be flexible, with multiple points of access, like a widget on your website, a Facebook Business Page, or a custom URL. For this reason, I tested each app from both the business and client sides.

When testing each app for this article, I signed up for an account and created a custom booking page for myself and my "team." I then explored the booking process from the client side, booking appointments with myself and watching for confirmation messages. Finally, I checked for ease of use, professional presentation, and bonus features like client and business management tools.

The best appointment schedulers at a glance

Best appointment scheduling app for ease of use

Acuity Scheduling (Android, iOS, Web)

Acuity Scheduling pros:

• Easy to use, even for beginners

• "Look busy" setting keeps you from looking desperate

• Plenty of templates and integrations

Acuity Scheduling cons

• No free plan

• Booking page isn't as customizable as other options

Now a part of Squarespace, Acuity Scheduling is the appointment scheduling app to choose when you aren't tech-savvy but still need to customize your booking process to a fine degree. When you design your booking page, you can allow your clients to choose recurring appointments (if applicable), complete an intake form, and pay in advance for services. You can also offer coupons and give clients the ability to add on services when they book, such as adding a 15-minute foot massage to a pedicure.

I found Acuity's blend of flexibility and ease of use truly impressive. During setup, you'll choose between monthly and daily view for clients, create intake forms, upload a logo, set a time zone, and decide whether to make clients pick their own time zone to avoid remote-call issues.

You can choose to let clients reschedule or cancel their appointments—or not—and change the interval for start times of appointments, which is by default every 15 minutes. You can put a limit on how far in advance or with how much short notice clients can book an appointment. And I especially love that you can enable an option called "Look busy," which automatically hides some available times so you don't seem desperate.

When you're ready, you can share your booking page via a direct link, embed it into your website using a few different options (including an easy embed option for Squarespace sites), or create a booking button, booking bar, or QR code. You can even set up the Reserve with Google feature to allow clients to book with you directly from Google Search or Maps. Acuity also has mobile apps to access your account from the business side, letting you update your availability from an Android or iOS device, and a client app for mobile booking.

I was impressed with the number of email templates that were available based on different appointment types, including confirmations, reminders, cancellations, rescheduling requests, follow-ups, package/gift card orders, and subscription updates.

Acuity also comes with powerful integration options, including QuickBooks, ClassPass, Salesforce, and Zoom. Or you can integrate Acuity Scheduling with Zapier, which lets you connect Acuity to thousands of other apps.

Supported payment systems: PayPal, Square, or Stripe; also works with in-person payments

Supported calendars: Google Calendar, iCloud, Microsoft Exchange, Office 365, Outlook.com; with the option to choose between 2-way and 1-way syncing

Acuity Scheduling pricing: Paid plans from $16/month for 1 staff member and location, payment processing features, and more

Best free scheduling app

Setmore (Web, macOS, Windows, iOS, Android)

Setmore pros:

• Extremely generous free plan

• Plenty of payment and integration options

• Mobile app with virtual "Cash register" point-of-sale system

Setmore cons:

• Lacking advanced features like coupons and intake forms

• Calendar sync is only 1-way on the free plan

If you're looking for a booking app that'll get you client-ready—in a hurry and for $0—you can't go wrong with Setmore. The app's free plan is the most generous option I found, including unlimited appointments, four users, customizable booking pages and notifications, and a number of useful native integrations.

Setmore doesn't have the most advanced features (you can't offer coupons or attach intake forms to your booking pages, for example). But what it lacks in features, it more than makes up for with setup speed.  After creating an account, select Settings to customize your booking page, team availability, scheduling rules, and payment processing. Then, open the sidebar menu and select Calendar to view your full schedule of booked appointments and classes. 

I found the default booking page to be slick and professional-looking, and you can upload a banner image and logo. And, with pre-built widgets for Facebook, Instagram, Reserve with Google, and several website builders, you can let clients book from nearly anywhere. Setmore's Zapier integration also lets you connect your booking tool to your most-used apps, from your email to your CRM and beyond. Here are some examples.

Supported payment systems: Square, Stripe, PayPal, LawPay, and cash accounting

Supported calendars: 1-way sync with Google Calendar and Office 365 on the free plan. Get 2-way sync on the paid plans.

Setmore pricing: Free for up to 4 team members and unlimited bookings; paid plans start at $5/month and include additional team members and locations, advanced integrations, recurring appointments, and more.

Best mobile booking app with built-in POS

Square Appointments (Android, iOS, Web)

Square Appointments pros:

• Built-in point-of-sale (POS) functionality

• Beautiful, streamlined interface built for mobile

• Resource management and commission tracking

Square Appointments cons:

• Google Calendar is the only calendar sync option

• Square is the only supported payment processor

Anyone who's paid for drinks at a coffee shop is likely familiar with Square's popular point-of-sale (POS) tech. Square also offers its own Appointments feature, which is a useful addition for retail businesses looking for an appointment scheduler with built-in POS functionality.

In fact, Square offers several features that small retail businesses might find useful within a single app, including flexible payment options (with the option to purchase POS hardware), online and in-person booking, staff management tools, and a client management database.

As any mobile-first platform would be, the Appointments module prioritizes aesthetics. Both the backend and customer-facing interfaces are clean and streamlined, and I was impressed to see that the tool encourages new users to upload photos for their products and services.

The free plan is frankly impressive for businesses with one location. But the paid plans also offer multiple locations, multi-staff appointments, resource management, and commission tracking—which make it easy to manage a complex service-based business with multiple providers.

And by connecting Square to Zapier, you can create automated workflows between your most-used apps. Learn more about how to automate Square, or get started with one of these pre-made templates.

Supported payment systems: Square (The payment processing system is quite robust regardless; you can easily order POS hardware through Square and print receipts with custom branding for your customers.)

Supported calendars: Google Calendar

Square Appointments pricing: Free for a single location. Paid plans start at $29/month per location for Google Calendar sync, automated confirmations, and waitlist functionality.

Best appointment scheduling app for international businesses

SimplyBook.me (Android, iOS, Web)

SimplyBook.me pros:

• 30+ languages and 35+ payment gateways

• Professional and customizable booking pages

• "Book soon" reminders and loyalty systems to encourage repeat customers

SimplyBook.me cons:

• All subscriptions plans limit the number of bookings per month (50 on the free plan; 500 on the standard tier)

• User interface isn't the most intuitive

Because of how many languages and international payment options it supports, SimplyBook.me is the best scheduling app for international businesses. SimplyBook.me's booking pages are available in more than 30 different languages, from Arabic to Greek to Indonesian to Xhosa. It also offers integration with Stripe, Square, PayPal, and multiple international payment processing services, so you can offer a system that works for your customers.

I found the setup process (and booking page) to be extremely pleasant and intuitive, as clear instructions walk you through your options for creating appointment types and add-on services. Choose a color theme and background for your booking page website, and specify how many service providers and services your business offers. As an added bonus, SimplyBook.me automatically identifies the features most relevant to you based on the information you added about your business category (for example, if you select "Gym," SimplyBook.me highlights selling memberships, offering classes, and including multiple locations). It even automatically generates an AI-powered description for your booking page.

And because SimplyBook.me is so conscious of the global business community, it only makes sense that it offers Facebook and Instagram integrations, too, for people who do most of their business through social media.

SimplyBook.me also offers a dashboard and reports, so you can monitor your business: see how many bookings have been canceled, workload per employee, online reviews of your business, as well as all the text message reminders that have gone out from your account.

Plus, you can connect your booking software to all the other apps you use for your business with SimplyBook.me's Zapier integrations. Do things like automate and customize your booking confirmations, add appointments to all your calendars, and more.

Supported payment systems: 35+ options, including Square, Stripe, PayPal, TapPay, Virtual Card Services, 2Checkout, Alipay, Asiapay, Authorize.net, Bitcoin, and more.

Supported calendars: Google Calendar, Outlook

SimplyBook.me pricing: Free for up to 50 bookings per month and 1 provider; paid plans start at $8.25/month for additional monthly bookings and providers, a branded client app, and more.

Best appointment scheduling app that doubles as an affordable website builder

Book Like A Boss (Web)

Book Like A Boss pros:

• Works well as a standalone eCommerce website and scheduler for new businesses

• Plenty of calendar sync and integration options

Book Like A Boss cons:

• Many features may be unnecessary if you already have a traditional website

• Expensive if you want to charge for bookings

If you're running a small service-based business or startup with an extremely limited budget, Book Like A Boss could be an affordable way to kill two birds with one stone. The platform lets users create unlimited booking pages for meetings and appointments, events, classes, and products. You can even add text-only pages, meaning you can use Book Like A Boss as your business's starter website. It's not as customizable or feature-rich as a WordPress site would be, but if you're cash-strapped and need a quick way to start selling your products or services, Book Like a Boss could be for you.

That being said, if you're already paying for website hosting and just need a cheap way to schedule (and charge for) appointments, be warned that BLAB users can only accept payments on the third-tier plan ($16.66/month). And then at that level, you won't have a custom domain anymore—you'd have to upgrade to the $25/month plan for that. While this price is a steal for a combo website builder, scheduling software, and eCommerce tool, it's far from the lowest price on this list for a standalone appointment scheduling app.

When I started testing this tool, I was a little thrown by the bright color scheme and—perhaps too corny for some—language. But Book Like A Boss functions a lot like a WordPress dashboard, so it was quick for me to get started. 

You can create unique booking pages for each appointment type, product or service, or event you offer. Set your custom booking schedule, then customize your page settings by choosing photos, skins, and the right colors and fonts for your brand. You can even add reviews, FAQs, and About Me and sidebar text for your mini-website's "home page."

The tool's robust native integrations let you connect to multiple tools like Google Analytics, Zoom, and Mailchimp. And with the platform's Zapier integration, it's easy to automate Book Like A Boss no matter what tools are in your tech stack. Here are some examples.

Supported payment systems: Stripe, PayPal, Square

Supported calendars: Google Calendar, Microsoft Exchange, Outlook, iCloud, Office 365

Book Like A Boss pricing: Freelancer plans start at $8.33/month for free meetings or $16.66/month to charge for bookings. Team plans start at$35/month for three users.

Other options for appointment scheduling

Dedicated standalone booking apps like the ones I chose aren't the only way to book appointments. If none of my picks work for you, here are some other options:

• If you host your website on WordPress, there are plenty of plugins that let your website visitors book appointments. Take a look at our picks for the best WordPress booking plugins.

• There are lots of niche apps that might serve you. For example, I found one app, QRappointments, to be a useful option for mobile businesses that want to display a booking QR code on their vans. These kinds of tools are definitely worth checking out if you have more specific booking needs.

• And then, of course, there's Calendly. I love Calendly and wholeheartedly recommend it for meeting scheduling. While meeting scheduling tools share some similarities with appointment software (they both let guests schedule time with you), the key difference is that appointment schedulers are more customer-focused and designed for both on-location and virtual bookings. They often offer a variety of appointment types that may or may not include a menu of services, but usually require payment at the end. Calendly does a lot of what you'd need from an appointment scheduling app, but it's much more geared toward meetings. If you're looking for a tool to let your clients, coworkers, and prospects schedule meetings with you, check out our roundup of the best meeting scheduling apps.

Do you need a booking app?

Whether you run a client-based business on your own or with the help of many staff members, you can find the right app to help you manage your client appointments. Using a full-featured appointment booking tool can also cut down on the number of no-shows and late cancellations, and it can help you recoup cancellation fees easily by securing a credit card hold at the time of booking. And when you automate your booking software, you'll be able to use your energy to focus on the work that matters most.
