Built a Stock Trading UI with Slot-Machine Digit Flip in React Native 📈

flips independently like a slot machine reel 📈

No library. No native module. Just Reanimated + a

vertical strip of 0–9 behind an overflow:hidden clip.

Price updates every 2.8s → each digit animates to its

new position with spring physics. The whole price

component is under 40 lines.

Stack used:

→ React Native Reanimated

→ react-native-svg for the chart
