How should a desktop application be adapted for mobile devices?

A mobile application must be designed for small screens first. The mobile design should not just shrink the desktop version. It needs its own layout and interactions.

The rule

A mobile application must be designed for small screens first.

The mobile design should not just shrink the desktop version. It needs its own layout and interactions.

A mobile application must be designed specifically for mobile screens. The main application area should not scroll. Instead, use a fixed bottom navigation bar for main sections. Use sliding panels from the bottom for extra features. This keeps the user from getting lost on a long page. The mobile design must use the same colors and fonts as the desktop version. This keeps the brand looking the same. Text must be easy to read. Use clear, high-contrast colors. Avoid small fonts or italics for main text.

A developer is building a mobile version of a writing tool. The desktop version has many panels open at once. For mobile, the developer creates a bottom menu bar. This bar lets the user switch between writing, editing, and finding ideas. When the user needs to change settings, a panel slides up from the bottom. This keeps the main screen clear for writing. The mobile app uses the same dark background and bright text as the desktop app.
