Nutrition and habits, then a pivot
2025
A personal tracker that treated meals as small, medium, or large. Archived after the interesting question moved into Chewsr.
The idea
A nutrition and habit tracker that refused to become a calorie spreadsheet. Meals were small, medium, or large. The point was showing up, not weighing chicken.
Why I built it
I wanted a daily object I would actually open. Most health apps punish you for being approximate. I am approximate.
How it works
You tap breakfast, lunch, dinner, and a few habits. Portions were sizes, not grams. There was a settings page, billing experiments, the usual product clothing on a personal tool.

What I learned
I learned that it’s a very fun problem to solve, but the space is immensely crowded, and was not sure that my personal favorite way to track was going to take off over more avant garde stuff like CalAI, etc.
Current state
Archived. Paused on purpose, not abandoned in shame. The domain still exists. Pivoted toward Chewsr.
