Roommate Coordination App

House Rules is an iOS app that turns roommate agreements into a living system. I designed and built it end-to-end — UX, UI, and the SwiftUI + Firebase stack underneath. The goal was to make shared-living rules feel light enough that housemates actually use them.

The icon was built in Apple Icon Composer around structured lists inside a house silhouette — a single mark that reads at every size and tells the product story in one glance. The 5-second light/dark swap is a small craft moment, not a gimmick.

Real life breaks schedules. Housemates can bump an overdue chore to push the deadline 24 hours, pass it for someone else to claim, or let it auto-open to everyone when it lapses. Accountability stays intact without becoming punitive.

Any rule change needs consensus from every housemate before it takes effect. The approval flow is a notification and a one-tap response — light enough not to bottleneck minor updates, structured enough that no one can change the rules unilaterally.

SwiftUI on iOS with an MVVM-flavored architecture and observable view models. Firebase handles auth, real-time sync, and storage; Cloud Functions handle anything that shouldn't live on-device. Real-time listeners keep every connected device in lockstep, so a chore marked done on one phone updates the others immediately.
