J2ObjC vs NativeScript: What are the differences?

Developers describe J2ObjC as "Java to iOS Objective-C translation tool and runtime used by Google Inbox to share 70% of its code across Android, iOS, and Web". J2ObjC is an open-source command-line tool from Google that translates Java code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java code to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as data access, or application logic) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. On the other hand, NativeScript is detailed as "Build truly native apps with JavaScript". NativeScript enables developers to build native apps for iOS, Android and Windows Universal while sharing the application code across the platforms. When building the application UI, developers use our libraries, which abstract the differences between the native platforms.

J2ObjC and NativeScript can be categorized as "Cross-Platform Mobile Development" tools.

"Backed by Google" is the top reason why over 3 developers like J2ObjC, while over 55 developers mention "Access to the entire native api" as the leading cause for choosing NativeScript.

J2ObjC and NativeScript are both open source tools. It seems that NativeScript with 17.2K GitHub stars and 1.27K forks on GitHub has more adoption than J2ObjC with 5.47K GitHub stars and 771 GitHub forks.

Hello,

We're just brainstorming for the moment and we have a few questions.

We have an idea for an app that we want to develop, here are the prerequisites:

1) cross-platform (iOS, Android, and website);

2) as easy to maintain as possible / well documented / widely used;

3) Visual Studio Code and Copilot compatible;

4) Text to speech;

5) Speech recognition;

6) Running in background (screen off with TTS and speech recognition);

7) could be using TypeScript;

8) Monetized through ad and in-App payment for premium version;

9) Display on lock screen (Android only I guess)

So what would you recommend?

I've been trying to review the options available, and I've considered:

  • NativeScript

  • React Native

  • Flutter

  • Any other?

Thanks in advance for your help, and I'm open to any comments.

Use Flutter and Firebase as a backend service, Firebase also helps to speed up the development and rollout of the app. The cloud-hosted NoSQL database provides a real-time database that helps you store and synchronize data between the clients. This indeed makes it easier for you to access the data using any of the devices.

Hi there, for cross-platform functionality in terms of 3D assets if any, echo3D can help you with that. It's 3D asset management on the cloud so you can write your references to the objects and update them in the echo3D web browser. echo3D is not yet on this platform but it will be soon!

As a startup, we need the maximum flexibility and the ability to reach our customers in a more suitable way. So a hybrid application approach is the best because it allows you to develop a cross-platform application in a unique codebase. The choice behind Ionic is Angular, I think that angular is the best framework to develop a complex application that needs a lot of service interaction, its modularity forces you (the developer) to write the code in the correct way, so it can be maintainable and reusable.
