Flatapps family mark: three equal app tiles, middle cyan

Architectural flatness

The file is the truth.

The app is a tool.

Software that refuses to become the owner of the thing it helps you make.

Position

Small tools for files you own.

Flatapps is the home for FlatNote, FlatGrid, and Flat Voice — one set of flat apps.

Flat doesn't ask you to move into Flat. The filesystem is the ecosystem.

Flat is a family of small, native tools built around files you already own. Notes stay Markdown. Tables stay CSV. Dictation stays on your device. Your folders remain folders. No proprietary formats, unnecessary accounts, silent conversions, or cloud dependencies. The app helps. The file remains yours.

If you need a neighborhood, we sit near people who keep work on disk. The point is flatter: collapse the abstraction stack so there is no invisible ontology underneath.

.md

FlatNote

Your notes are files. As they should be.

notes/*.md

FlatGrid

The grid is the CSV. Free on iPhone, iPad, and Mac.

Flat Voice

Nothing essential lives on a server you don't run.

  • 01No account. There isn't anything an account would do for you.
  • 02Your notes are files. As they should be.
  • 03FlatGrid never guesses.
  • 04If we disappear, your files don't.

Six Flat laws

Concise · not a manifesto dump

  1. 01

    The user's artifact is canonical.

    The file wins. The app may show, sort, or prettify. It does not become the original.

  2. 02

    Use boring, durable formats.

    Markdown, CSV, TXT, TSV, JSON, folders. Formats you can open without us.

  3. 03

    Don't infer without permission.

    00123 stays 00123. A leading zero is not a suggestion. Guessing is a feature request, not a default.

  4. 04

    Don't require infrastructure you don't need.

    No account. There isn't anything an account would do for you.

  5. 05

    Apps compose through artifacts, not platforms.

    Same folder. Matching filenames. The filesystem is the ecosystem.

  6. 06

    If the app disappeared tomorrow, the work remains useful.

    Not “can I export?” — was it ever trapped?

Flat Out

Notes on software that stays out of the way

Editorial, not a changelog. Short pieces on accounts, export buttons, silent correction, folders, and who gets to be the source of truth.
