Build an app people open every day.
On November 15, 180 builders take over the YC office to build consumer mobile apps in one day.
Consumer apps are having a moment again, and AI has collapsed the time it takes to build one. Come build the app you'd actually want on your home screen, ship it to a real phone by dinner, and demo it to founders and a YC partner who've built consumer products used by millions.
You'll build with Capy, Revyl and Convex, with the Candle team (a YC consumer app with 1M+ users) on the floor all day helping with what makes people come back.
The winning team gets a YC interview. Breakfast, lunch anddinner are on us.
What to build
A consumer app for iOS or Android that someone would want to open again tomorrow. You don't need to ship to the App Store, but it needs to run on a device so you can demo it live.
Tracks
We'll have themed tracks with their own prizes, on top of the overall top 3. Tracks and track prizes will be announced at kickoff, so come with ideas, not code.
Prizes
1st place: a YC interview, plus an iPhone 18 Pro for every team member
2nd place: a MacBook Neo for every team member
3rd place: an Apple Watch for every team member
Track prizes: announced at kickoff on the day.
