Creating a cross platform mobile application

October 3, 2025

I'll talk about the tech and the challenges one faces if they want to create an app. This post is just an overview and doesn't go in depth in any of the topic mentioned. It'll only give you an Idea of what all things you need if you want to develop and publish an app today.

What is a cross platform mobile application?

If you want to create an application that works on both IOS and Android.

What it takes to publish an app?

Its not very hard to publish an app once you have the idea in your mind, but don’t get me wrong its a different story when you want to make that app successful. The framework you need to create and publish an app is:

• Ideation
• Idea Validation
• Design
• Code
• Publish

Ideation

Think of an idea

Idea Validation

You need to validate the idea, but this is optional if you’re still learning.

Design

If you’re not a designer just use an AI tool to create the design.

Code

Use React Native to build the app, this is the best framework you can use to build a cross platform application.

Publish

• Apple Store: You’ll need an app store developer account, You can submit your app for review right away. It’ll take about a week for the testing from app store to finish and you might be asked to do some revisions. After this the app gets published.

• Play Store: Need a play store account and unlike App Store here you’ll have to first conduct internal testing of the app with atleast 14 people enrolled for testing. After the testing period is over then only you can submit your app for production release. This usually doesn’t require much revisions as you’re testers will already tell you about the bugs.

The hardest part of making an app is the marketing, even if you’ve the best tech and design you won’t get any downloads as long as people don’t know about the app.
