Principles
The product rules behind every release.
Clear first contact
The interface should explain itself fast. People should feel capable before they feel impressed.
Privacy without qualifiers
No trackers, no ads, and no monetization tricks hiding behind polished language.
Native speed
Animations, gestures, and layout all need to feel like they belong on Apple platforms.
Focused scope
Each app earns its place by doing a small number of jobs very well, not by chasing feature inflation.
