⭐️⭐️⭐️⭐️⭐️ • "BEST APP EVER! I have found this tremendously helpful in my work. It has saved me a ton of back and forth trying to figure out when I can meet with people." - Rev. Rebekah

⭐️⭐️⭐️⭐️⭐️ • "Excellent product. Reliable, robust, and the best's free!" - Dominic Iannucci

⭐️⭐️⭐️⭐️⭐️ • "Teacher friends, this Koalendar extension is a game changer for conferences. You can send them links to sign up + even ask a question  “what would you like to discuss during our conference today?” And it syncs to your calendar. You can do 1:1, capping it at 1/slot or do small groups!" -Emilie Drapeau

⭐️⭐️⭐️⭐️⭐️ • "I love Koalendar. It's perfect for my tutoring students and my business. It has saved hours in my week going back and forth on when a good meeting time would be and booking it in my google calendar. It has also allowed my students to book up to a month ahead so that both of us can plan ahead. It has raised my overall branding and professionalism. All my students love the ease of use and I love that it sends me updates on when someone books and where they would like the lesson to take place. The aesthetics of the booking link are much more appealing than other booking websites that I looked at. It has fewer clicks for the client and the mobile version is great as well. I would highly recommend this program for anyone who has regular bookings with clients." - Alissa Forbes
