Build your own Finch with Claude Code

A self-care pet app: a pet that grows as you do self-care, daily goals, mood check-ins and more.

WeekendA working first version in a day or two

The Claude Code prompt

Build my own take on Finch: a self-care pet app. Give it an original name, logo, colours and copy, and do not use Finch's name, branding or assets.

Version one should have:
- A pet that grows as you do self-care
- Daily goals
- Mood check-ins
- Journaling
- Rewards

The hard part: Art and charm. Spend time on the character.

How to build it:
1. Read this folder first. If it is empty, set up Next.js (App Router, TypeScript, Tailwind) with Postgres through Prisma or Supabase, and Supabase Auth or Auth.js for sign-in. Write a short PLAN.md with the data model, screens, third-party services and what you are leaving out of version one.
2. Build the core loop end to end before anything else: a pet that grows as you do self-care, working with real data saved to the database.
3. Add the rest of the features one at a time, and seed realistic demo data so every screen looks alive.
4. Keep API keys in environment variables, and put any paid service behind a small interface with a local stub, so the app runs on a fresh machine without accounts.
5. Run it, click through every screen on desktop and mobile widths, fix what breaks, and finish with a summary of what works, what is stubbed and how to deploy it.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.

Version one

  • A pet that grows as you do self-care
  • Daily goals
  • Mood check-ins
  • Journaling
  • Rewards

The hard part

Art and charm. Spend time on the character.

Make it yours: a niche Finch ignores, an original name and brand, and one feature it does badly done well.
