## What it is
A React Native library that runs timers and emits periodic events even when the app is in the background, on both Android and iOS. It provides background-safe setTimeout/setInterval equivalents plus cross-platform run/stop background timer APIs.

## Use cases
- run periodic tasks in a react native app while backgrounded
- keep a timer running when the app goes to background on ios
- schedule background polling every few seconds on android
- execute javascript code in background in react native
- background countdown or interval timer for mobile app

## When to choose
- you need periodic background execution in a React Native app on Android and iOS
- you want a drop-in replacement for setTimeout/setInterval that survives backgrounding

## When to avoid
- you need long-running background services beyond periodic timers
- you use Expo without ejecting, since native modules are required
- you need background location or audio features rather than timers
