The lab. One new idea a day.

Small experiments from who else? Free to use, no login. Real counts only.

• Tue Nov 3 · #22Got next? who else?Pickup at the park. Pick a sport and a time, see the nearest public courts and fields, and post “We need 1 more, 6:30” or tap “I’m in” to hold a spot for 20 minutes. Basketball, soccer, volleyball, tennis and ultimate. Hourly weather, and a flag for unlit courts after dark. DC, NYC and SF. 18+.
• Wed Nov 4 · #21Airport split who else?Same flight time. Half the cab. Find people leaving your neighborhood for the same airport in the same 30 minutes, meet at a public station and split one cab. Fare estimates from city taxi rates and live FAA airport status. DC, NYC and SF. 18+.
• Mon Nov 2 · #20Curb it who else?Free on the curb. Gone by dinner. One photo, a block not an address, and “On my way.”
• Mon Nov 2 · #19Jam who else?Bring your instrument. Pick a public park and a daytime slot, see which seats in the band are open, and take one at your level: guitar, bass, drums, keys, voice, horns, strings or anything acoustic. Weather check and three easy songs to start. DC, NYC and SF. 18+.
• Mon Nov 2 · #18Lost it? who else?Left it on the train? Someone may have picked it up. Tap what you lost, then the line or neighborhood, and see how many found cards match. Found one? Put up a card with one hidden detail and hand it back at a police station or library. DC, NYC and SF. 18+.
• Mon Nov 2 · #17Stargazing who else?Look up tonight. Pick your city to see tonight’s clouds, the Moon and which planets are up, worked out from free public data. See how many people are looking up too, then meet at a public spot with posted night hours, or go to a club’s free star party. DC, NYC and SF. 18+.
• Mon Nov 2 · #16Job who else?Apply alone. Hunt together. Pick your role and city to see how many people are hunting for the same kind of job this week, tap I’m hunting too, then sit down together for an hour or two at a public library. Real NYC city openings and official job-center links. No resumes, no names. DC, NYC and SF. 18+.
• Sun Nov 1 · #15Housing who else?Same block. Same budget. Same hunt. Apartment: tap a building on the map to see how many people are on your exact search, then tap Me too. House: plan your open-house Saturday. Flat share: index cards, person first, no address, no chat. DC, NYC and SF. 18+.
• Fri Oct 30 · #6Book club who else?Say which book you’re reading and your page. See who else is reading it, behind, near or ahead of you. Later reactions stay hidden until you get there. Start a small club with a private link.
• Fri Oct 30 · #7Dogs who else?Check in at a public dog park and see who else is there now. Free buddy walks, walkers and sitters, with any money arranged between you, never through the app. Walk weather and sunset. 18+.
• Fri Oct 30 · #8Cowork who else?Check in at a library, café or coworking spot, say “here till 4,” and see who else is working there today. Heads-down or up for a coffee break. A labeled AI work buddy when it’s empty. 18+.
• Fri Oct 30 · #9Language exchange who else?Say what you speak and what you want to practice, post a one-hour swap at a library or café this week, and see who fits: their language is yours to learn, and the other way round. A labeled AI practice partner when nobody does. 18+.
• Fri Oct 30 · #10Board games who else?Post a table at a game café, games bar or library: the game, the time and the seats. Others tap to take a seat, and the table disappears when it ends. 18+.
• Fri Oct 30 · #11Volunteer who else?Post a park cleanup, beach cleanup, garden day or litter walk at a public park, beach or community garden, in daylight, or cards for neighbors at a library. Others tap “I’m coming”, and afterwards it shows how many people said they’d come. 18+.
• Fri Oct 30 · #12Language tutor who else?Find a person who tutors your language for an hour this week at a library or café, free or at their own rate, or practice now with a free ✦ AI tutor that runs on your phone. People always first. 18+.
• Fri Oct 30 · #13I voted who else?For the Nov 3 midterms: tap “I’m voting today”, “I voted early or by mail” or “I voted”, make a sticker on your phone, and see self-reported taps by area. Links only to official polling-place lookups. Nonpartisan. 18+.
• Sat Oct 31 · #14Trick-or-treat who else?Halloween night: neighbors say “Our block is giving out candy” for their block, never a house, and families see which blocks nearby are lit. Sunset, the 5–9 PM forecast and a 30–45 minute walking loop. Posts from 30 minutes before sunset until 9 PM. 18+ to post.
• Thu Oct 29 · #4Jogging who else?Pick a public running spot, a start time and your pace, and see how many runners plan to start there. Share a private link with friends. 18+, counts only.
