PRICING

ScheduleOnce is an appointment scheduling software that you can use for yourself or with a team. It lets you create a calendar with all your available times. It integrates with calendar apps so you and your client can receive automatic notifications. Integration with Zoom, Microsoft Teams, Webex, Google Meet, and more allows the platform to create automatic video links for online meetings. While it’s feature-packed, the interface can be challenging to configure. Be sure to allot time to customize and explore to make the most out of it.
Koalendar is a great ScheduleOnce alternative because it offers a clean, modern, and intuitive interface, for free.
Your invitees will get a delightful booking experience along with a customizable questionnaire to qualify them. You'll also enjoy a live and quick customer service, directly from the developer.
But don't take our word for it: feel free to try Koalendar's free forever account .
Testimonials
Thousands of teachers and business owners are enjoying the benefits of using a simple online appointments scheduling software.
“We’ve doubled our attendance rates and number of bookings, reduced the time we spent on scheduling by like 12 hours per person, per week, and everything is completely customized with our school’s colors and logo.”


“I use Koalendar to schedule tutoring session with students. I was able to get it set up and sent to students in about 5 minutes. Support was extremely friendly and is a real person rather than a robot or outsourced.”
“I was looking for a free, easy manageable and customisable calendar app for ages. Koalendar offers all that. So I have recommended the app already to 2 of my colleagues.”
“Koalendar has made scheduling meetings and calls so much easier. I no longer have to send over an email with all of the dates/times I am free. I just simply send a link and they can see the times I have open. I love it!”
“This has been a great tool to schedule virtual appointments with my students. I am able to easily provide a link under my signature in my email and on Google Classroom. Students can easily set up an appointment that works for them. This has been a tool for keeping appointments organized.”
“When Doodle dropped their calendar sharing support, I tried different tools but they all didn't provide the features I was looking for. Eventually I found Koalendar and it's exactly what I need. It has a free version, it's easy but flexible to configure and people wanting to book a meeting with me can do it fast and easy.”
“This software has changed the way I hire and interview new hires. With Koalendat it allows the candidates to self-schedule themselves for the interview day.”

OnceHub highlights a Starter/Basic experience for individuals (e.g., 1 user, 1 connected calendar, and 1 booking link), with a 14-day trial to explore advanced features. It’s solid for testing, but teams quickly need paid tiers.
Cost and complexity at higher tiers, or a desire for simpler branding/admin and multiple pages per user without steep per-seat pricing.
Powerful routing and enterprise features come with plan tiers that add up as you scale. The free experience is limited to one user, one connected calendar, and one booking link, so teams graduate to paid plans quickly.
