I have used Calendly for the past 2 years. I wanted to switch to TidyCal almost right away but I did not. 2 years later here I am and I am happy with my lifetime purchase which is the same a 1.5 months of Calendly payments. WOW!!!! I am excited to continue using it. My only suggestions would be to have text message feature added instead of just email notification and reminders and maybe add an additional reminder but overall I am happy with this so far for what I Paid. I have already started recommending it to my colleagues. Thank you and let's continue to make it even BETTER!!!
