About this animation
A countdown timer in React Native can make a genuinely time-limited offer clear without mixing business logic into every screen. This paywall takes an absolute expiresAt value, derives the remaining time from it, and calls onExpire when the clock reaches zero. Use it for a one-time upgrade offer, reservation window, trial extension, or another promotion with a real deadline. Reanimated and Expo Linear Gradient provide the polished urgency treatment while the displayed time updates independently from UI-thread motion. The component highlights the final ten seconds, exposes a direct onClaim action, and keeps the remaining time available as a concise accessibility summary. Its small public API makes the offer logic easy to connect to an existing purchase flow.
When to use it
- Present a genuine limited-time upgrade offer.
- Show a reservation or checkout hold.
- Count down a trial extension.
- Trigger expiration logic at zero.
