I use Sunsama for this already and have used Timepage (iOS app) in the past. Neither are free, but both have polish and extra features that imo make them worth what you do pay.
I also couldn’t find the pricing info, so I just blindly signed up for the closed beta. I’ve been guided through a short form, at the end of which I’ve learned that after a 14 day trial Sunsama will cost $20 a month (!), even for personal or any other non-commercial use.
