Hearth

A zen habit tracker for iPhone where your consistency feeds a living flame — and the whole app changes mood with the time of day.

Hearth turns small daily rituals into lasting change. It pairs a forgiving streak model with a Higgsfield-rendered fire that grows from embers to a blaze based on real 7-day momentum, adaptive morning/midday/evening/night themes, six languages, and an optional Plus tier sold through StoreKit 2.

Time-of-day adaptive themes and a non-punishing streak engine
Free tier plus subscription / lifetime unlock via StoreKit 2

3D Block Builder

A 3D brick planning tool I built to solve my own problem — designing a garden wall with a fixed set of differently shaped stones.

I had a fixed inventory of stones in multiple shapes and sizes and needed to plan a wall that used all of them without buying more. No tool existed for this, so I used Claude to build exactly what I needed. The result is a full 3D builder with grid snapping, gravity physics, supply tracking, and 2D/3D view modes.

Built with Claude to solve a real-world constraint problem

My personal portfolio and blog, featuring an interactive web-based OS with built-in apps and a terminal.

This site is more than a portfolio. It includes a blog system, a custom design language, and a browser-based OS environment with a terminal, file system, ChrisPaint, Snake, and 2048.
