What services do you use to build your mobile app?

NativeScript Vue. Then reuse 90% of the code for Vue.js web app if needed.
For simple backend - Firestore. For more advanced and custom stuff - Python/Django REST API or Node.js. Might include AWS Lambda.

Using React Native + Expo was a wonderful experience. I was able to move very quickly (it helps if you have familiarity with React), and deploy on iOS and Android quickly.

I'm using Flutter and Firebase for my mobile app.

Any stack will do in the right hands ;)

But right now I'm using this as my favorite for getting offf the ground quickly:

• Flutter for cross platform (faster than ReactNative/Xamarin/other)
• Firebase for auth/database
• .Net Core / Azure for some additional API handling when needed

The last part could probably get cheaper with some other cloud system, but that's the technology I know, so I stick with it as it saves me a lot of time.

UI's are built in Clojurescript and pacakged with cordova to deploy to devices.

For local persistence I've been using localForage since it integrates easily with SQLLite. Haven't noticed any data problems with that setup.

Backends are done in Clojure, and deployed to Heroku or AWS depending on my needs. I've setup some boilerplate for my projects that handles APIs as well as realtime websocket type stuff; so it's pretty easy to get something up and running quickly.

If I need additional server persistence I generally jump between MySQL or Mongo depending on what I'm saving. I've found these sufficient for my needs.

For me:

• Xcode
• Swift
• TestFlight
• Probably Firebase eventually 🤷‍♂️

I use Flutter

In my opinion, it highly depends on the client's requirements. There are three setups I can choose from:

• Fully native (Java/Kotling for Android and Obj-C/Swift for iOS)
• Hybrid (Native UI but cross-platform like React Native/NativeScript/Xamarin etc.)
• Web-based (solely in the browser, not native at all like Ionic, Cordova, PhoneGap etc.)

Let's say you have developers with same experience in all three setups, what would you recommend? If performance is crucial and you're fetching tons of data, then only native will satisfy you/your client. If you have JS developers available with existing knowledge in one of the big UI frameworks (React, Angular, Vue) you definitely wanna go with hybrid apps, as the performance and look-and-feel are almost native, but the codebase is "web-like". Finally, if you have no idea about the mobile ecosystem on either Android nor iOS, stick to web-based frameworks as the output for a lot of clients is just fine (they often don't recognize the difference, which hurts mobile devs a lot).

My personal favorites in the different sections are the following:

• Swift for iOS (& I guess Kotling for Android, but I don't really do that)
• React Native for cross-platform (Community is huge, you get everything that you need and Facebook under the hood has the power to carry on that project for a long time)
• Ionic for PWAs

As I'm a huge advocate of cloud computing so I would definitely go for Firebase as backend, hosting, API, storage (or whatever, Firebase does it all) system and React Native as a mobile framework.

EDIT: Therefore you need a setup like:

• VS Code as editor
• XCode/Android Studio for native stuff
• JavaScript/TypeScript and React
• NodeJS for the backend
• Firebase

Have ALWAYS used Xamarin and always will. Have deployed 50+ apps with that stack and it keeps getting better and better. For that last 5+ years I've used Xamarin Forms, which is absolutely brilliant to make real cross platform code.

For backend work I use primarely .Net Core, which again is amazing.

And yes, I am a C# lover and always will be ;-)

Starting with a carrd.co site, used HTML, css and JS to get randomhiit.app working.

Its not a web stack but for mobile development I highly recommend Xamarin. Works really well and also you have the nice side effect that a single code base is used for iOS and Android. i.e. Develop once and run everywhere.

Highly recommended.
