# Zero Redux DevTools

Our awesome new Zero Rating SDK is based on a Redux/Saga Library, and part of the reason for it is the amazing DevTools we can add around it.
State & Sagas visibility, manipulation, and even time-machine.
Comes as a Flipper Plugin to Android first, then iOS.

Inspired by JavaScript's [Redux DevTools @ GitHub](https://github.com/reduxjs/redux-devtools).

## This Diff
