We are developing an AWS IoT app for large boats. The IoT devices have sensors all over the boat for engine oil pressure, position, water depth, fuel level, crew location, etc. When the boat has internet, we interact with AWS cloud using lambda and Amazon DynamoDB. When the boat is offshore, the captain and crew still need normal and emergency alerts and real-time sensor information. The crew might have an Android or IoS phone or a Windows or macOS PC to receive alerts and interact with sensors. We may use the AWS GreenGrasss edge computing solution and either MQTT or HTML for that function.

Question: We want to develop a cross-platform client to run on Windows, Mac, Android, IOS, and possibly Linux. We are primarily Python programmers, so PyQt or Kivy are options for us, but we have heard good things about React Native, Flutter, Xamarin, and others. We think an AWS Greengrass core on an RPI4 could communicate to the client with MQTT or a local webserver with a client web interface.

Any thoughts would be much appreciated.

React Native

I don't know much about Xamarin but I know about PyQt and React Native.

However, I don't recommend PyQt because the apps made using PyQt are not that suitable for mobile apps. If you take a look at the PyQt interface, you will be able to see that the features are more of a desktop apps kind.

React Native uses JavaScript. React Native is immensely flexible in upgrading your apps because it allows you to formulate your app code into independent blocks.

In Xamarin, you have to write the code in .NET . The best thing about Xamarin is, that it extends the.NET developer platform with tools and libraries specifically for building apps for Android, iOS, tvOS, watchOS, macOS, and Windows

While the best choice for you depends on various factors but React Native app development is a promising overall choice. In today’s scenario, React Native has steady growth, flawless code structure, and brilliant and large community support. We suggest you go for React Native for your next project owing to its outstanding support from developers, easy availability, and cost-effectiveness.

It seems like your app is not really using any native functionality on the phone. I have experience with cross platform iOS & Android development. They are all really good tools! Xamarin (all the project on the website portfolio I attached) is awesome for accessing native functionality (NFC, Sensors, Bluetooth, etc), and I have built apps that have millions of downloads, some that hit Top 5 on Utilities, another that hit Top 50 in Finances. You just have to look at what your application intent is, it seems like it's just to read and post data. For that they are all pretty good, but you should also look into Ionic which may serve the same purpose
