expo-symbols vs Other Icon Options: Choosing Icons for a React Native App

Icons look like a small UI decision until a product needs to support iOS, Android, accessibility, theming, and a consistent visual language. In an Expo app, expo-symbols is attractive because it uses the platform's native symbol systems. But it is not automatically the best choice for every icon.

The practical decision is less about which package has the largest catalog and more about where the icon's meaning and visual identity come from: the operating system, your design system, or your product's own artwork.

What expo-symbols brings

Install it with the Expo-compatible version of the package:

Installation

npx expo install expo-symbols

Then render a native symbol with SymbolView:

Native symbol

      import { SymbolView } from 'expo-symbols';

export function FavoriteButtonIcon({ active }: { active: boolean }) {
  return (
    <SymbolView
      name={active ? 'heart.fill' : 'heart'}
      tintColor={active ? '#c62828' : '#5f6368'}
      size={24}
    />
  );
}
    

On Apple platforms, names such as heart.fill map to SF Symbols. On Android, Expo maps the component to the platform's Material Symbols implementation where supported. The result is a native-looking icon rather than a web font or an image copied from another platform.

That is the main advantage: expo-symbols is a good fit for familiar system actions such as favorite, share, delete, search, and settings. It can also follow platform conventions more naturally than a single icon set forced onto both operating systems.

The important limitation: names are not universal

A symbol name that is meaningful in SF Symbols is not necessarily available in Material Symbols, and the two systems do not always have identical shapes or weights. That means a symbol-driven UI needs a compatibility plan.

Keep platform-specific names behind a small component instead of scattering them through screens:

Semantic icon mapping

      import { Platform } from 'react-native';
import { SymbolView } from 'expo-symbols';

const iconNames = {
  search: Platform.select({
    ios: 'magnifyingglass',
    android: 'search',
    default: 'search',
  }),
};

export function SearchIcon() {
  return <SymbolView name={iconNames.search} tintColor="#202124" size={22} />;
}
    

This wrapper gives the design system one semantic name, search, while the platform mapping stays in one place. Test both platforms before choosing less common symbols, especially when an icon is part of navigation or a high-value action.

How the main alternatives compare

Option	Best fit	Main tradeoff
expo-symbols	Native system actions and platform-aware UI	Symbol catalogs and appearance differ by platform
@expo/vector-icons	Fast access to familiar cross-platform icon fonts	Font glyphs can feel less native and add font-based behavior
react-native-svg	Branded icons and custom vector artwork	You own assets, sizing, accessibility, and consistency
lucide-react-native	A coherent open icon set with component APIs	The visual language is product-owned, not platform-native
Image assets	Complex illustrations or fixed artwork	Scaling, tinting, and high-density variants need more care

Where the alternatives fit

1 @expo/vector-icons

It is often the quickest choice for prototypes and utility screens. Its broad catalog is useful when a project already uses one icon set consistently, but font loading and platform sameness become part of the tradeoff.

2 react-native-svg

Use SVG when an icon is part of your brand or must match a design file exactly. You gain control, but you also own stroke widths, dark mode, view boxes, and accessibility behavior.

3 Lucide and component libraries

A library such as lucide-react-native is a useful middle ground: real vector components, a consistent outline style, and no raw path management. Its style becomes part of your product language.

A practical selection rule

Use expo-symbols when the icon represents a platform convention and a close cross-platform match is acceptable. Use a component icon library when you want one coherent visual language across both platforms. Use SVG for brand-specific marks and custom illustrations. Keep font icons for existing projects or broad, low-risk coverage where their tradeoffs are already understood.

For accessibility, do not let an icon carry an important action without a label on the control that owns it:

Accessible icon button

      import { Pressable } from 'react-native';
import { SymbolView } from 'expo-symbols';

export function CloseButton({ onPress }: { onPress: () => void }) {
  return (
    <Pressable accessibilityRole="button" accessibilityLabel="Close" onPress={onPress}>
      <SymbolView name="xmark" tintColor="#202124" size={22} />
    </Pressable>
  );
}
    

The icon package is only one part of the decision. The durable choice is the one that keeps icon semantics centralized, survives both platform builds, and remains understandable to people using a screen reader.

Bottom line

expo-symbols is compelling when native platform character is a feature. It reduces the distance between a React Native UI and the conventions users already know, especially for standard actions. It is less compelling as a universal replacement for custom artwork or a cross-platform design system.

Choose by semantic role: native symbols for system actions, a consistent vector library for product UI, and SVG or images for identity. That small distinction prevents an icon package from becoming an accidental architecture decision.
