Transcripts

Releasing a mobile app can be tricky, with tough  rules that could delay our launch. In this video,  

we'll guide you through releasing  an app on both iOS and Android.

Grab a notepad—we're about to share essential  tips and tricks to navigate these challenges  

and release a smooth, efficient app that  users will enjoy. Let's get started!

To start building our iOS app, we first  need to join Apple's Developer Program,  

which comes with an annual fee.

For Android, we register as developers on the  

Google Play Console and pay  a one-time registration fee.

Next, we choose our programming language:  

Swift or Objective-C for iOS,  and Java or Kotlin for Android.

We write our apps with key development tools like  Xcode for iOS and Android Studio for Android.

Alternatively, we might opt for a cross-platform  development tool like React Native or Flutter.

These let us write code once  and deploy it on both platforms.

They can speed up development and reduce costs.

However, they might not always offer the same  

performance or access to device-specific  features as native development.

Once we've written our code,  it's time to build and test.

We compile our app's binary and conduct thorough  

testing using tools like XCTest  for iOS and Espresso for Android.

Device farms help us to automate testing  across hundreds of device configurations,  

catching issues that could affect different  hardware or OS versions. This automation is  

integrated into our CI/CD pipelines to  streamline the build and test process.

Our goal is to deliver top-notch  quality and performance across all  

devices, aiming for a rock-solid release  candidate build ready for the next stage.

It’s important to mention that while  device farms like AWS Device Farm or  

BrowserStack provide significant  benefits, they can be expensive.

Their use might be planned later  in the development cycle based  

on budget allowances and project requirements. 

Quality Assurance The next stage is QA.

It starts with internal alpha  testing to catch initial bugs,  

followed by "dogfooding," where  the team uses the app extensively.

After this, we invite a group of users  to try the app and provide feedback  

through beta testing platforms like Apple’s  TestFlight and Google Play beta testing.

It’s important to note that TestFlight limits us  

to 10,000 testers, and Google Play  has similar constraints. We need to  

choose our external testers carefully  to gain the most meaningful insights.

These platforms help us gather feedback  under real-world conditions and identify  

any issues that didn't surface  during earlier testing stages.

Before we submit our app to the stores,  we need to obtain internal approvals.

This requires getting the green  light from key stakeholders,  

focusing on criteria like UX consistency, brand  alignment, and technical performance metrics.

We also need to make sure our app meets  all the necessary app store guidelines  

and adheres to industry regulations on  security practices and privacy compliance.

App Store Optimization is about making  our app more visible in the app stores.

It involves optimizing our app's metadata,  such as titles, descriptions, and keywords,  

and localizing our content for different regions  to boost search rankings and attract more users.

It’s also important to design  eye-catching screenshots and  

icons that showcase our app's best features.

When it comes to release notes,  

get creative and highlight all the  exciting new updates and improvements.

Now comes the moment of truth: App Submission.

For iOS, we submit our app  through App Store Connect,  

closely following Apple's strict guidelines.

Android developers will proceed via the Google  Play Console, adhering to Google's policies.

Prepare for potential delays and be  patient—especially if this is a new app.

The app review teams sometimes may  seem unreasonably picky. They may  

request changes or additional information, so it's  

important to allow extra time for this  phase to ensure we secure approval.

Finally, it's time to  release our app to the world!

If possible, coordinate a simultaneous  launch on both iOS and Android platforms.  

Make sure our marketing efforts are  in full swing to generate buzz and  

anticipation for the launch. This can maximize  our visibility and impact right out of the gate.

But the journey doesn't end there.

Once our app is live, it's crucial to  monitor user feedback and analytics.

We use this data to improve and update the app,  

fixing bugs and adding new  features based on user demand.

We also engage with users  through reviews and social  

media to build a loyal community around the app.
