Simple by Default boot
App boots into a focused metering screen, not a feature wall.
Where to find it
Viewfinder (default destination on launch)
Summary
First launch lands you on the viewfinder with a live preview, the most-used controls in plain sight, and everything else tucked behind icons and tabs. New users do not have to dismiss tutorials or pick a mode before they can take a reading.
How it works
What you see on first launch
A live camera preview, a focal length slider, an aperture/shutter readout, and two rows of icons across the bottom for the most-used toggles. That is the whole opening surface. You can take a meter reading without opening anything else.
Why this default
The app carries a lot of features (zone system, calculators, cine mode, darkroom, alt process, ML detection). Showing them all at once would overwhelm a new user who just wants to meter a scene. So the default screen hides depth behind icons; you only meet a feature when you tap the icon for it.
How to go deeper
Each icon on the viewfinder opens a focused modal: Tools, Metering Mode, Layers, Filters, and so on. Each modal is self-contained, so you can dip in, change a setting, and return to the same metering session. No deep menu paths.
Where the rest of the app lives
Tabs across the top of various modals reach the heavier surfaces: Tools tab for film tools, Logs tab for shot history and analytics, Settings for global preferences. You will not stumble into them by accident.
