What app do you use to schedule meetings, and why?

I'm building TimeTuna.com (it's a beautiful Calendly alternative) and I'm curious to know what tools you guys use and why.

Currently, we're focusing primarily on the aesthetics of the product and making it easier (less awkward) to share your link and making it more personal and less transactional.

We don't know if this will work long-term, revenue-wise. But if WeTransfer can make sending files exciting, we can make scheduling meetings exciting.

We might need to pivot to a more B2B approach in the future to get more revenue. But we haven't decided yet.

Curious to hear your thoughts!
