What exactly do I get at the end of the design stage?
The screen map with approved flows, the theme applied inside the project (palette, typography, spacing, components), the app icon and splash screen in every required size, plus the dark-mode variant. It is all already in the editor, not in a separate file someone has to reimplement.
Can I change the colours after launch?
Yes, from a single place. The palette is defined at theme level and components inherit it, so changing the accent colour shows on every screen without touching them one by one. Theme changes need no new build unless you alter the structure.
How do you show the design before the build?
In the editor preview, on your own phone: you open a link, navigate through real screens and give feedback on flows, not on static images. Corrections go straight into the project, so what you approve is exactly what gets compiled.
Will the app look the same on iPhone and Android?
Consistent, not identical. Colours, typography, spacing and screen structure are the same; switches, menus and transitions follow each system conventions, because users spot an element that behaves foreign straight away.
Do we need a designer on our side?
No. If you already have a visual identity — colours, typeface, logo — we turn it into a theme. If you do not, we start from a predefined theme, adapt it to your field and refine it over one or two feedback rounds.
Does design matter for store acceptance?
It does. Apple regularly rejects apps with an unfinished interface, empty screens without explanation, or navigation that leads nowhere. A design that covers every state significantly lowers the risk of rejection at first review.
