How an app gets made
Every app we make goes through the same stages, whatever it does.
Sketch
We start from a job people need done, check what already exists, and draw the screens in pencil.
Design
Every screen in light and dark, for phones and tablets, with the real text of each language.
Build
Native code, tests that run on every change, and release builds that anyone on the team can repeat.
Release
Store pages, screenshots and privacy policies in each language, then the store’s review.
After launch the work goes on: fixes, new features, and an inbox that people answer.
What every app gets
Every app we make has clear prices and no ads. It asks only for the permissions its job needs, ships in five languages or more, works on phones and tablets in light and dark, and keeps getting updates after launch.
