UNRELIABLE Today I got a message that my booking system was down. Instead of informing me that my live link was down calendly has just been letting the URL bounce for who knows how long because they wanted me to upgrade my plan. I have no idea how much money this cost me but I'll never recommend this service to anyone. Incredibly poor handling and I'll be sure to mention this at every Miami tech event I find myself at.

Did not add value, caused much pain. I signed up for a free trial at the request of our recruiters. First ding: it required a connection to my Google Calendar to start the trial. Despite requiring this, it didn't actually use *any* of the information in the calendar to actually help - it didn't apply my timezone - it didn't pick up any current meetings to block out time Second ding: Changing the timezone of the meeting I set up was *deeply* non-obvious. Third ding: I have had *incessant* spam emails from them ever since signing up for the trial. Would not use in the future, even if you paid me - literally a completely useless tool.

Absolute trash Absolute trash. The Optometry practice I work at uses this and it is utter rubbish to use! It's clunky, not user friendly, it doesn't sync with calendars properly so there are always conflicting or double bookings which ends up causing numerous complaints from patients. I would not recommend this as it is poorly written.

Terrible service I ended up with a free trial when I neither need nor requested one (fell into it while trying to accept an appointment). I then spent half an hour trying to extract myself from this with no help from anyone other than robots and repetitive advice. I was unable to get anyone to help or provide me with someone who could help properly. Disgraceful. Would never use or recommend!

Waste of time and money Calendly worked fine until they started 'upgrading' the software. Now it's WAY to messy and complicated and nothing works. Classic case of software engineers adding new features and making 'improvements' just for the sake of it. Now I can't even generate a simple one-off invite with specific dates and times. Won't sync with iCal either. Spent hours with various agents on the Chat trying to fix it – to no avail. I'm out. Never again.
