In development

The wellbeing apps. Each one turns a stream of small entries into one honest number, and uses the Claude API for the parts that need reading, not arithmetic.

  • In development · Claude API

    Millet

    Photograph the grocery receipt; Millet reads it into the week's nutrition against a WHO band. Claude does the structured extraction and food matching. Numbers, never advice.

  • In development · Claude API

    Budgie

    One question each morning: what can I spend today? Claude classifies the day's transactions so the answer is ready before coffee.

  • Principle

    Wellbeing, not diagnosis

    These apps show and compare numbers. They never diagnose, score your health, or tell you what to do. That line is fixed.

Built with Claude

One developer ships like a team because Claude does the typing and the reading.

  • Claude Code, every app

    All four App Store apps and every tool on this page were built with Claude Code, from first commit to App Review replies.

  • Claude API, the next apps

    Structured extraction from receipts and labels, transaction classification, and short narrated explainers. Small, typed calls where code needs to read.

  • Careful by design

    Data stays on the phone unless the user sends it. No ads, no trackers, and nothing that reads your health for you.

Web tools

Free, browser-only tools, no install and no account.

  • Beta · webcam

    flamingo

    How old is your balance? Stand on one leg in front of your webcam; it times you, measures sway, and reads the result against published norms for ages 18 to 99. Video never leaves the browser.

  • Interactive

    Dementia risk check

    Fourteen things linked to dementia that people can change, defined and sourced from the 2024 Lancet Commission, with what helps for each.

  • Game

    Two faces in one picture

    Mix two faces into one, walk away, and watch them swap. A game about how your eyes see big shapes and tiny details.

About

Founded and run by one developer in Toronto, a PhD candidate in vision science and healthy ageing. The studio is where that research becomes something you can hold: small, honest apps for eating, spending, balance and memory.
