Number Flow React Native

The best animated number component for React Native.

Features

• Beautiful digit-by-digit rolling — each digit animates independently via virtual wheels with automatic direction detection
• Two renderers — a default View-based renderer with zero dependencies, and a Skia renderer if you need to have Skia numbers animating
• Full Intl.NumberFormat — currencies, percentages, units, compact notation, and everything that this beautiful formatter has to offer
• TimeFlow — dedicated animated time display with 12h/24h, timestamps, and countdown support. Even supports centiseconds.
• 120 FPS scrubbing — worklet-driven updates entirely on the UI thread, with Skia.
• 37 numeral systems — Arabic-Indic, Devanagari, Thai, CJK, and more.
• Accessibility — VoiceOver/TalkBack announcements + reduce motion support
• Continuous mode — odometer-style cascading digit rolls

Installation

# npm
npm install number-flow-react-native react-native-reanimated

# bun
bun add number-flow-react-native react-native-reanimated

# expo
npx expo install number-flow-react-native react-native-reanimated

Quick start

import { NumberFlow } from "number-flow-react-native";

function PriceDisplay() {
  const [price, setPrice] = useState(42.99);

  return (
    <NumberFlow
      value={price}
      format={{ style: "currency", currency: "USD" }}
      style={{ fontSize: 32, color: "#000" }}
    />
  );
}

Renderers

The default import uses the View-based renderer — no extra dependencies needed. If you need to display numbers in Skia Canvas, use the Skia renderer:

// View-based (default)
import { NumberFlow, TimeFlow } from "number-flow-react-native";

// Skia canvas (requires @shopify/react-native-skia)
import { SkiaNumberFlow, SkiaTimeFlow, useSkiaFont } from "number-flow-react-native/skia";
