Harmonizely Review

Harmonizely is an online appointment scheduling tool that focuses on seamless integration with CalDAV-based calendars as well as Google, iCloud, Outlook/Office 365, Zoho, Zimbra, FastMail, Daylite, and others. Instead of forcing you into a single provider, it connects to the calendars you already use and exposes your availability through a clean, shareable scheduling page.

The platform is aimed at freelancers, consultants, and teams who want to cut down on back-and-forth emails and let clients pick meeting times that work for everyone. Harmonizely is a small, self-funded SaaS company based in Poland, and its roadmap is clearly influenced by feedback from decision-makers who use the product daily.

From the first visit to the homepage, the emphasis is on saving time, boosting engagement, and avoiding unnecessary emails through automated scheduling flows. The interface is straightforward, with clear calls to action to sign up for free and start scheduling meetings in just a few clicks.

Harmonizely’s core value proposition is its CalDAV-first scheduling approach, which is rare among appointment tools that often assume you use Google Calendar. By supporting Google, iCloud, Outlook/Office 365, Zoho, Zimbra, FastMail, Daylite, Kopano, and generic CalDAV calendars, it becomes a unifying layer for users with more complex or privacy-focused setups.

The platform promises to help individuals and companies turn leads into revenue by removing friction from booking meetings. Invitees simply receive a link, choose from available times, and Harmonizely handles the rest, including calendar updates and notifications.

For teams, Harmonizely adds round-robin scheduling, centralized billing, and shared settings to streamline how multiple people handle inbound meetings. This makes it particularly attractive for sales, recruitment, and customer success teams that need predictable, low-friction scheduling at scale.

Harmonizely offers a broad set of calendar integrations, connecting with Google Calendar, iCloud, Outlook/Office 365, FastMail, Zoho, Zimbra, Daylite, Kopano, and other CalDAV solutions. This makes it especially useful for users who rely on privacy-focused or enterprise calendars that many competitors ignore. All meetings and calendars can be managed from one scheduling app, reducing confusion and context switching.

The platform includes smart scheduling features such as one-on-one meetings, availability control, buffer times before and after meetings, and limits on how soon or how far into the future invitees can book. Time zones are automatically detected so invitees always see times in their local zone, and the scheduling page is multilingual, supporting more than 15 languages including English, Italian, Polish, French, Swedish, German, Portuguese (Brazil), Norwegian, and Spanish.

Customization is a strong point, with options for secret meeting types, private notes, customizable scheduling page appearance, and customizable email notifications. You can remove Harmonizely branding, use a custom domain, set a custom email sender, and add your company logo to maintain a fully on-brand experience.

On the automation side, Harmonizely integrates with Zapier, enabling connections to Slack, Gmail, Google Sheets, InfusionSoft, MailChimp, Pipedrive, and hundreds of other tools. It also supports video conferencing integrations with Zoom, Microsoft Teams, Whereby, Kopano Meet, and Google Meet, automatically generating unique meeting links for each scheduled event.

For teams, Harmonizely adds organization management, round-robin scheduling, centralized billing, and the ability to clone settings across members’ accounts. This makes it easier to onboard new team members, maintain consistent scheduling rules, and manage roles and permissions from a single place.

Harmonizely’s pricing is structured around four main tiers: Free, Pro, Premium, and Enterprise, with monthly and annual billing options. The Free plan is designed for individuals getting started, while Pro and Premium target small and growing businesses, and Enterprise covers highly customized deployments. A 14-day free trial of Pro features is available without requiring a credit card.

The Free plan includes one calendar, one meeting type, and core integrations with Google, iCloud, Outlook/Office 365, Zoho, Zimbra, FastMail, Daylite, Kopano, and other CalDAV calendars. It also supports unlimited meetings, email notifications, multilingual scheduling pages, timezone synchronization, secret meeting types, private notes, and controls over how soon or how far out meetings can be scheduled.

The Pro plan, listed at $9.99 per user per month on the pricing page, builds on Free by adding three calendars per user, unlimited meeting types, calendar notifications, Zapier integration, Stripe integration, additional participants per meeting, buffer times, invitee questions, Zoom and Google Meet integrations, Kopano Meet integration, Facebook Pixel and Google Analytics tracking, redirect to external confirmation pages, meeting rescheduling, customizable email notifications, customizable scheduling page appearance, removable Harmonizely branding, custom domain, custom email sender, company logo, email reminders, Microsoft Teams integration, organization management, and round-robin scheduling.

The Premium plan is priced at $11.99 per user per month and includes everything in Pro plus support for six calendars per user and email verification. This tier is aimed at growing businesses that need more complex calendar setups and additional verification workflows.

Finally, the Enterprise plan offers custom pricing and includes everything in Pro along with personal onboarding, priority support, annual contracts, and custom features and integrations. This makes it suitable for organizations that require tailored workflows, security reviews, or bespoke integrations beyond what is available out of the box.

Harmonizely highlights several customer testimonials that emphasize its CalDAV support, design quality, and impact on scheduling efficiency. One testimonial from Hans van Gent, Founder and Chief Strategist at User Growth, notes that Harmonizely provides a beautiful, on-brand experience on his own domain, allowing clients to book meetings directly into his calendar while praising the support and pace of feature development.

Another testimonial from Chris Hardie, Director of Special Projects at Automattic, states that Harmonizely was perceived as the only well-designed tool in its category that does not assume Google Calendar and supports the CalDAV standard for syncing. This reinforces the product’s positioning as a niche-friendly yet polished alternative to mainstream schedulers.

Karol Wójciszko, CEO at Fresh Apps, shares that Harmonizely was found to speed up the process of scheduling customer calls and interviews with potential employees, which in turn was said to convert into more leads. On the pricing page, Ben Murray, Founder at The SaaS CFO, mentions that Harmonizely made it simple for clients and prospects to book time with him and praises its calendar management capabilities.

Beyond on-site testimonials, Harmonizely encourages visitors to check “a few dozens of reviews on Capterra” and references G2 Crowd as another source of social proof. This suggests a broader base of user feedback, particularly among SaaS, consulting, and remote-work professionals who rely heavily on efficient scheduling.

From a usability perspective, Harmonizely delivers a clean and focused scheduling experience that does not overwhelm new users. The interface for creating meeting types, controlling availability, and connecting calendars is intuitive, and the ability to manage everything from a single dashboard reduces friction for busy professionals. The multilingual scheduling page and automatic timezone detection further improve the experience for international clients.

The strongest differentiator is Harmonizely’s deep CalDAV support, which makes it a standout choice for users of iCloud, FastMail, Zoho, Zimbra, Daylite, and other non-Google calendars. Many competing tools either ignore these providers or offer unreliable workarounds, so Harmonizely fills an important niche. Its integrations with Zoom, Microsoft Teams, Whereby, Kopano Meet, and Google Meet also make it a solid fit for remote-first teams.

On the downside, Harmonizely’s website structure shows some legacy or broken pages, such as FAQ and certain legal URLs returning “Uh oh. That page doesn’t exist.” This can create a slightly fragmented impression compared to larger competitors with more polished marketing sites. Additionally, while the feature set is robust, the ecosystem and brand recognition are smaller than giants like Calendly, which may matter for organizations that prioritize vendor maturity.

Overall, Harmonizely offers an excellent balance of functionality, customization, and price, especially for CalDAV users and small to mid-sized teams. If your workflow depends on non-Google calendars or you need fine-grained control over branding and scheduling rules, it is a compelling option that deserves serious consideration.

Harmonizely is a specialized yet capable scheduling platform that shines when you need reliable CalDAV support and flexible branding options. Its Free plan is generous, and the Pro and Premium tiers add a deep set of integrations and automation features at a competitive price point. Enterprise customers gain access to personal onboarding, priority support, and custom integrations, making it viable even for more demanding environments.

The main trade-offs are its smaller ecosystem and some rough edges in the marketing site structure, which may be noticed by users comparing it to larger incumbents. However, the core product experience, calendar coverage, and customer testimonials suggest a mature and actively developed solution. For consultants, agencies, and teams that care about calendar diversity and on-brand scheduling, Harmonizely is easy to recommend.

Taking all factors into account—features, pricing, usability, and customer feedback—Harmonizely earns a strong rating for its category. It is particularly well-suited to professionals who have outgrown basic scheduling tools and need a more flexible, CalDAV-aware alternative without enterprise-level complexity.
