Found it very easy to use and to incorporate into my website. It has a lot of features that I like and very few that I don't. A feature that I do like and that is 'days ahead.
Minimum meeting padding or buffer.'

Customer service is very good. I sent an email to TidyCal and they replied in a decent amount of time and said they would take the followig pointd to their developers.

1) Allow scheduled meetings to be less than 15mins in length. It is not flexible to book 15+ mins slots. At times I would like to book, 5, 10, etc. But the product doesn't allow it.

2) Add the feature to enable customers to choose 'SLOT NUMBER'. I am a professional photographer and often allow customers to book photoshoots after certain events. Whilst you can book in 8.15, 8.30, 8.45, etc. It would be helpful to book in slots instead; for example Slot 1, 2, 3 , 4 etc. Because customers may have different amount of people in their party and thus one slot might take 6 mins, another, 3, another 7 etc.
