App in a Day

From idea to deployed app in a single working session. Web, mobile, or both.

What You Get

A working application — deployed and accessible — built in a single focused day. Not a mockup. Not a prototype that needs "more work." A real app your users can start using.

Deliverables

  • Deployed application — Live on the web, ready to share
  • Core functionality — The 2-3 features that matter most, working end-to-end
  • User authentication — Sign up, sign in, password reset (if needed)
  • Clean, responsive UI — Works on desktop and mobile
  • Source code — Yours to keep, modify, and extend
  • Deployment documentation — How to update, maintain, and scale

What We Can Build

  • Internal tools — Dashboards, admin panels, data entry apps
  • Customer-facing apps — Portals, booking systems, directories
  • Mobile apps — iOS + Android from a single codebase (Expo/React Native)
  • Landing pages — With forms, payments, or integrations

The Process

  1. 30-min kickoff call — We scope the app together, prioritize features
  2. 4-hour build session — I build while you're available for quick decisions
  3. Deployment + handoff — App goes live, you get documentation and source code

Why This Works

Modern tooling makes this possible:

  • AI-assisted development — Claude writes production-quality code in minutes
  • Pre-built components — Authentication, databases, UI — all ready to wire up
  • Instant deployment — Vercel, Expo, Supabase — live in seconds

What used to take a team two weeks now takes one person half a day.

Best For

  • Validating ideas before investing heavily
  • Internal tools that "nobody has time to build"
  • MVPs that need to exist for a demo or pitch
  • Replacing spreadsheet workflows with proper apps

Recent Example: Charter Direct

Built a boat charter booking platform in 48 hours that cuts operator fees by 90%. Full Stripe integration, scraped competitor data to pre-build operator pages, deployed to production.

What This Isn't

  • Complex enterprise software (that's a different engagement)
  • Apps requiring extensive third-party integrations
  • Native iOS/Android with platform-specific features

One app per day. Book your slot.
