I wanted to build an Airbnb for storage. So I built NOOK.

Live app: TestFlight GitHub: github.com/lopezsellesarnau-cmd/nook-app

NOOK is a two-sided marketplace where hosts rent out spare space — basements, garages, spare rooms — and tenants reserve it by the month.

It works on iOS and uses Firebase for real-time data, Stripe Connect for host payouts, and Cloud Functions to process payments securely.

The app has a clean editorial look — white background, Inter typography, 47px card radius, and a minimal black/white design language that makes listings feel premium instead of classified-ad cheap.

This makes it easy for hosts to list their space in minutes and for tenants to browse, reserve, and pay without leaving the app.

The app handles both sides of the marketplace — host identity verification via Stripe onboarding, reservation approval flow, real-time chat between host and tenant, and a full payment pipeline with service fees.

It uses Firebase Cloud Functions as the backend so the whole thing runs serverless with no infra to manage.

With NOOK, anyone with spare space can start earning in under 10 minutes.

My process: Figma wireframes → Design system → Flutter screens → Firebase backend → Stripe Connect integration → Cloud Functions → TestFlight
