Two practices, one habit.
The app and the page that explains it get the same attention.
Apps
Native iOS apps and small web apps. Each one does a single job and is finished before it ships.
No accounts unless the app needs one. No tracking.
Marketing
An app is also its store listing, its screenshots, its support page, and the sentence that explains it. We write and build those too.
Static sites that load fast and carry no scripts. Copy that says what the thing is.
