Catalog 2023—2026

Independent software,
deliberately made.

STARCK is an independent software company founded by Soren Starck. It makes focused products, and the infrastructure behind them, for people who care about their tools.

Selected work

S/002 · S/003 · S/008

01 Selected

Three products carrying STARCK at the moment. Each has its own identity, its own site and its own audience.

Catalog number S 002

SessionWatcher (opens in a new tab)

Know where your AI coding usage stands.

Usage, cost and rate-limit windows for a dozen coding assistants, live in the menu bar. It exists because the first time you learn you are out of quota should not be mid-sentence.

macOSActive2025

sessionwatcher.com

Catalog number S 003

TurtleBar (opens in a new tab)

Know exactly when your Mac battery dies.

A time, not a percentage. Small enough to forget about, which is the correct amount of attention for a battery.

macOSActive2025

turtlebar.app

Catalog number S 008

Moorline (opens in a new tab)

Customer support built around closing the loop.

Support software that measures itself on whether the conversation actually ended, rather than on how fast the first reply went out.

moorline.app

02 Infrastructure

Built for STARCK’s own products first. Built independently. Designed to work together.

04 How things get made

Focused

A product needs one clear reason to exist. Everything after that reason has to argue for itself.

Independent

Each product stands on its own. None of them exists to complete a suite, and none requires another to be worth having.

Deliberate

Features, interactions and details earn their place or they are removed. Most of the work is removal.
