This project is to convert an Objective-C iOS database application to React Native so that it can be complied and deployed to both iOS and Android devices (of varying screen sizes). The application is currently live in the iOS store, you can download it by searching for: Realhound Commercial Real Estate CRM I'm very happy with the application and how it works. The only change I would like make to it is for it to be internationalized for language and some of the fields, such as changing Square Feet to Square Meters. The translation should be handled through a translation table that we have the ability to edit and add new fields too. All fields captions, headers, messages, etc. should come from the translation table. The app is responsive and works well on all sizes of iOS phones and iPads. We are looking for a pixel perfect replicate of the app, in React Native, that will work on both iOS and Android. You will be given access to the Objective-C source code. The database is in MongoDB which we host.

Hello Andrew, Just wanted to understand that if your iOS app works perfect and you already have it developed as a native app then what is the need of getting it done in React Native? As one of your platform is already covered for iOS, you have already invested on it then why go React native and not just native development on Android? Unless there are a lot of changes you have planned for the mobile app, I would think that going Native will be a better option and can be effective as it will at least save the time for testing on iOS and native means better experience! This is just coming out of curiosity, if iOS was not developed or was not working good then may be going with a cross platform solution would have been better but since app on iOS works perfect then Native can be the way to go for developing the Android version. Thanks, Ankit
