A React Native app uses Facebook’s open-source JavaScript framework. It allows for native API calls and the ability to write code once and then deploys it on iOS or Android.
That means there are a few things to consider when looking at how long it takes to develop a React Native app:
The complexity of your project
The features you want
The amount of support you need.
Let’s say you’re looking for something simple. You want a React Native app showing photos with captions. These types of apps can take one to two weeks to develop.
But if you want something complex, you’ll be looking at closer to two months.
Suppose your React Native app needs to be able to fit into existing systems. It will take even longer!
