Does not recommend this product
Great design, appreciate the work that has gone into this! Just because "you can" do something however, doesn't mean "you should". This concept actually does the opposite of making things simple, it actually adds hurdles to make it more difficult. Not trying to be mean and I hope this is considered constructive feedback for any innovators reading this, but no-one is ever going to adopt/use this product because most people figure out when to meet via voice, in person, using their brain, and/or via text/e-mail. Adding an app/service into the equation is just going to add unnecessary complexity. The entire concept is entirely superfluous. What kind of friends start a discussion about hanging out by sending them an invitation to "book" a time with them?! It's such a cold, unsociable, and drawn out experience! It just drives me crazy when people use their talents to create stuff that will never ever get off the ground. Feel free to come back in 12 months to prove me wrong but I just can't see this getting any traction.
