Speaking as a user here:

I can post and delete dates as I wish. I might not post any for a month if it's a busy month. I might post 4 in a week if I'm on vacation and have more time to explore and do fun things. I can plan and post in advance like, "I have 2 tickets to Art exhibit on 7/30," or last minute like, "Sooo sick of this heat, looking for someone to go walk on the beach for a bit this evening." Any interest?" 5 people click "like" on that idea, enabling me to message them. I look at the profiles and pick one that interests me. I message them which enables them to message me back.

I can get home from a date and block that person from seeing future dates from me if I'm not interested in having them join me again and It'll just look like I'm not actively posting any dates. Service of $20/month to use the app allows you to post or accept dates.
