In addition to developing mobile applications in Objective-C/Swift for iOS and Java for Android where it most suits the project, 1minus1 has adopted use of React Native to build mobile applications.
As it is developed further (and it is indeed a very new technology, having been initially presented by Facebook as a way to build native mobile applications in early 2015), it is becoming a better and better tool to use to keep costs down by creating mobile applications rapidly, and at quality. And with that comes cost reductions. Our current estimates of the time and therefore cost saving of using React Native is about 25%, and for a second application (for example if you went from having the first application for iOS and then developed the second for Android) allowing for significant reuse.
So yes, you may well – dependent on the kind of features your application needs – expect to be able to release applications across the separate platforms at a significant cost saving.
At 1minus1, we believe that React Native represents the future of mobile applications where you are using hybrid technology. You may also like to read this blog post we wrote about increasing mobile productivity using React Native.
