We update about every month. Currently we're on React Native 0.36, tomorrow we're submitting an update to the app store with 0.37. So we're usually at most 2 versions behind, although we cherry-pick in any very useful and stable commits in advance. For example, we had native animations on Android for months before they were in React Native core. There are talks about changing the React Native release cadence from bi-weekly to monthly, in which case we may adjust our release cycle to align more closely with it.
