Frequently Asked Questions (FAQs)

Which scheduling app is best for you?

The best scheduling app depends on your specific needs. For sales teams using Salesforce, Cirrus Insight Smart Scheduler is ideal for lead routing and CRM syncing. If you’re a solo consultant or small business owner, tools like Book Like A Boss or Calendly may be more appropriate. For those managing classes or recurring services, Picktime and Square Appointments are great options. Review the Top Appointment Scheduling Apps section to compare based on pricing, integrations, and use cases.

Do I need a scheduling app if I have a calendar app?

Yes—calendar apps are great for personal organization, but they don’t automate the booking process. Scheduling apps reduce manual coordination by letting others view your availability, book time, and receive automated confirmations and reminders. This helps prevent double-booking, improves time management, and creates a better experience for clients or teammates.

Is Calendly free to use?

Yes, Calendly offers a free plan that includes basic one-on-one meeting scheduling, calendar integrations, and email notifications. It’s a great starting point for individuals, though teams may need to upgrade to a paid plan for advanced features like round-robin scheduling, CRM integrations, and analytics.

Does Google have a free appointment scheduling tool?

Yes, Google offers a built-in appointment scheduling feature called Appointment Slots within Google Calendar (available for Google Workspace users). It allows people to reserve time on your calendar during open blocks you define. While it's helpful for basic needs, it lacks some of the advanced automation, customization, and branding features found in dedicated scheduling tools.

Which is the best scheduling app for iPhone?

Most major scheduling apps, including Cirrus Insight Smart Scheduler, Calendly, Square Appointments, and SimplyBook.me, offer full-featured iOS apps. For iPhone users who want mobile-first convenience with robust functionality, Square Appointments stands out for service businesses, while Calendly is best for one-time use.

Which is the best scheduling app for Android?

On Android, apps like Picktime, Zoho Bookings, and Cal.com offer solid performance. Picktime is particularly good for managing both bookings and invoicing on the go. If you need something developer-friendly or customizable, Cal.com offers open-source flexibility and Android compatibility.
