The most exhausting part of dating apps is finding out three weeks in that you wanted different things. Intent modes put the answer first.
Pick a mode — Tonight, This week, Slow, Open, Monogamish — and you join a feed of people who picked the same one. A check-in lasts 24 hours; then it expires and you can join again or not.
Matches made inside a mode carry a small note: "You both joined Tonight." No guessing.
