Testimonials
Professionals ❤️ Koalendar
See how professionals are using our booking website builder to save time and grow their business.
“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.”
