Tacit

Like Tinder, but for prices.

Swipe right for yes, left for no. No bidding wars.

Each side swipes on price cards, like an eye test. Nobody types a number, and nobody sees the other side’s answers. Anyone can open a room: the seller, the buyer, or a go-between such as an agent.

Open a room

Without a go-between, you’ll both see one suggested price once you both agree. Nobody sees the other’s answers.
Your own deal only Not on the list? Give a rough price and the cards ask about 70% to 130% of it. Each condition becomes a card. Both sides must say yes for it to count as agreed.
