“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.”
