The Steps to Build a Karaoke App

An illustration of the mobile app development process

We now take a detailed look at how to make a Karaoke app. Such a project involves the following steps:

1. Analyze popular apps and decide on the karaoke app features

A review of the following popular Karaoke apps will help you to understand how a Karaoke app works. Some of the best Karaoke apps include the following:


Smule is one of the most popular Karaoke apps. Karaoke has never been so much fun. Users can sing unlimited songs, including the latest and karaoke classics. It offers the following features:

  • Users can access a wide range of free songs and sing karaoke along.
  • They can collaborate with their friends across the world and make music videos on their favorite songs.
  • There is a free version of the app, and then there is a premium version. The paid version offers users unlimited access to 1 million songs from their favorite artists. Users can improve their singing skills and create duets.
  • Smule offers web, Android, and iOS apps.
  • They offer in-app purchases.

Red Karaoke

Red Karaoke is among the popular and free karaoke apps. It is available on the web, Android, iOS, and several smart TV platforms. Red Karaoke has the following features:

  • Users can check out a large number of karaoke songs to sing duets and for group performances.
  • In-app purchases, user sign-up, and enabling Karaoke singing with friends are some of their other key features.


StarMaker is yet another popular app that lets you and your friends sing karaoke. Their notable features are as follows:

  • They have a large collection of music to choose from.
  • StarMaker Karaoke app is available on Android and iOS.
  • Users can record their songs with a range of voice effects.
  • One can enjoy Karaoke singing with friends from a growing list of new songs.
  • The app offers in-app purchases.

You should incorporate the following features in your karaoke app:

  • You should offer a large collection of modern and classical songs to your users, preferably across several genres.
  • Users should be able to record a video solo or with their friends on all the songs.
  • High-quality video streaming is important.
  • The app should allow users to customize the key and tempo of any song, add lead vocals, etc.
  • The app should offer in-app purchases and payment gateway integration.
  • The app should feature user sign-up and push notifications.
  • You should offer your app on the web, Android, and iOS platforms, to start with.
  • An attractive “User Interface” (UI) is important.

You can read “Top 15 best free Karaoke apps for Android and iOS” to understand why these features are important.

2. Agree on a project scope

I suggest the following scope for this project:

  • Web app development;
  • Android app development;
  • iOS app development.

You should include the features I have suggested.

3. Choose a project methodology

After launching an initial version in the market, you will likely add features based on the market response. You might even want to target smart TV platforms or expand into other geographies.

Such projects are good candidates for Agile methodology, and you can read “Waterfall vs. Agile: which methodology is right for your project” to understand why.

We call the initial version a “Minimum Viable Product” (MVP) in Agile parlance.

4. Onboard a project team

Your project team needs the following roles:

  • Business analysts (BAs);
  • UI designers;
  • Web developers with experience in Node.js;
  • Android developers with Kotlin expertise;
  • iOS developers with Swift skills;
  • Testers;
  • A project manager (PM).

I recommend that the PM manages this project using the “Scrum” technique, which is useful for Agile projects. Here, the iterations are called “Sprints”, and the PM acts as the “Scrum master”.

The scrum master forms cross-functional, small teams that are called “Scrum teams”. You can consult our guide “How to build a Scrum development team?” for more insights.

5. Prepare a development strategy

Your development strategy for this project should comprise the following:

  • You should use managed cloud service providers. This will enable you to focus on the development, and you won‘t get bogged down with infrastructure management.
  • Consider using market-leading “Software Development Kits”(SDKs) and “Application Programming Interfaces” (APIs) for key features, like accessing music, streaming, video recording, in-app purchase, payment gateway integration, etc. This way, you don‘t “reinvent the wheel”.

6. Procure managed cloud services for web app development

Several noted managed cloud service providers offer “Platform as a Service” (PaaS) for web app development. I recommend that you use one since it offers the following advantages:

  • PaaS providers manage the entire gamut of cloud infrastructure, including servers, networking, storage, etc.
  • They provide the operating system (OS), middleware, and runtime environment. This enables you to focus on coding.
  • PaaS providers offer “Application Performance Monitoring” (APM), auto-scaling, DevOps, databases, and several other services.
  • You can easily integrate 3rd party APIs with your app when you a PaaS platform.

Our guide “10 Top PaaS Providers” explains these advantages in detail. AWS has impressive cloud capabilities, therefore, I recommend that you use AWS Elastic Beanstalk, i.e., their PaaS offering.

7. Get managed cloud services for the mobile app backend

The development and ongoing management of the mobile backend take time and energy, however, you can use a “Mobile Backend as a Service” (MBaaS) to simplify this. MBaaS providers offer many advantages, e.g.:

  • They handle the cloud infrastructure fully, including networking, server, and persistent storage.
  • Scaling your Karaoke app will be easier with an MBaaS platform.
  • You can easily implement features like user management, security, and push notifications if you use an MBaaS platform.
  • Integrating 3rd party APIs and managing the complexity due to various mobile platforms and devices become easier with an MBaaS platform.

Read “How to choose the best Mobile Backend as a Service (MBaaS)?” to learn more about these advantages.

You can use AWS Amplify, which is the MBaaS offering from AWS. You need only one AWS account to use Amplify and Elastic Beanstalk. You also don‘t need to hire mobile backend developers and cloud platform architects.

8. Sign-up for Spotify SDKs/APIs

You need to provide a wide range of songs to your users. Spotify is a good solution. They offer the following features and advantages:

  • Spotify features a large collection of songs.
  • Audio analysis, playback, recommendations, search, playlists, etc., are some of their other features.
  • Your developers can use the Spotify web API for web app development.
  • Spotify offers an Android SDK, and there is an iOS SDK.

9. Procure video recording SDKs/APIs

Users of your app will record videos of their songs, moreover, they might collaborate with their friends for Karaoke. This requires an appropriate video recording solution at scale. I recommend that you use video recording SDKs/APIs from Twilio.

You can get the following features and advantages:

  • Twilio video recording platform offers video recording, peer-to-peer collaboration, group rooms, screen sharing, and several other useful features.
  • They offer SDKs for Android and iOS. You can use their JavaScript SDK for web app development.
  • Sign-up for the Twilio video platform here.
  • You can check out their pricing plans here.

10. Buy a cloud streaming solution

When you create a Karaoke app, you need a high-quality, low-latency cloud streaming solution. Wowza is a good choice for this due to the following reasons:

Their pricing plans are here.

11. Get an eCommerce solution

You need an eCommerce solution to implement the in-app purchase feature. Shopify is an excellent choice, offering the following advantages:

  • Shopify SDKs and APIs enable you to incorporate the entire range of eCommerce features.
  • You can get their Android and iOS SDKs here.
  • For web app development, you can access their JavaScript SDK here.
  • You can easily sign-up for the Shopify SDKs/APIs here.
  • Shopify offers extensive documentation for their SDKs and APIs, and you can find it here.

12. Sign-up with a payment gateway provider

A payment gateway integration can help the app users, therefore, I recommend that you use Braintree. Braintree is from PayPal. The following are the advantages of using Braintree:

13. Buy a bulk SMS solution

Engaging the users of your Karaoke app is important, and you need a bulk SMS solution for that. I recommend that you use Twilio, as follows:

  • You can sign-up for their “Programmable SMS” offering.
  • Read their detailed documentation here.
  • Check out their pricing plans here.

14. Web app development

Scalability and streaming are two key requirements of a Karaoke app. Node.js facilitates these, therefore, it‘s a great choice for web app development. There are other advantages too, e.g.:

  • js is easy to use for most developers since many programmers already know JavaScript.
  • A large and growing developer community has created many sharable tools and frameworks for this open-source runtime environment. This improves developer productivity.

Read “10 great tools for Node.Js software development” to learn more about the advantages of Node.js.

Proceed with web app development, as follows:

15. The mobile app UI design

You need to design an appealing UI for the mobile app, therefore, focus on the following aspects:

16. Use Kotlin to develop the Android app

Android developers are increasingly using the modern programming language Kotlin, and I recommend you do so too. Kotlin offers several advantages, e.g.:

  • The concise syntax of this open-source language reduces coding effort.
  • Kotlin is fully interoperable with Java and uses Java libraries.
  • Apps coded in Kotlin are fast since the Kotlin library is lightweight.
  • Maintaining apps written in Kotlin is easier.
  • The language helps developers prevent common errors like null pointer exceptions.

I have explained these and more advantages of Kotlin in “Kotlin vs Java: which is the best choice?”.

17. Develop, test, and deploy the Android app

Android app development involves the following:

  • Use Android Studio, which is the popular “Integrated Development Environment” (IDE) for Android development. It fully supports Kotlin.
  • Integrate music library, video recording, streaming, eCommerce, payment gateway, and bulk SMS SDKs/APIs in your app.
  • Test your app using Android Studio, and publish it to Google Play by following this guide.

18. Code, test, and deploy the iOS app

I suggest you use Swift, the modern programming language preferred by Apple for iOS app development. There are many advantages to this choice, e.g.:

  • Apps written in Swift are fast.
  • The language has powerful features like generics and operators like string concatenation. These improve the productivity of developers, moreover, bug-free coding becomes easier.
  • Swift reads just like English, therefore, the code is easier to maintain.

There are more advantages to Swift, and I have described them in “How to migrate your Objective-C project to Swift?”.

Develop the iOS app as follows:

  • Use Xcode as the IDE, which fully supports Swift.
  • Integrate Twilio video, Twilio SMS, Wowza cloud streaming, Shopify eCommerce, Spotify music library, and Braintree payment gateway SDKs and APIs in your code.
  • Test the app.
  • Publish the app to the Apple App Store using this guide.

19. Manage the project using effective tools

A scrum team works as follows:

  • A “Product owner” provides the requirements in a document called “Product Backlog”.
  • The team plans sprints by estimating and prioritizing the requirements.
  • The scrum master holds a “Daily stand-up meeting” to collect the project status and resolve issues.
  • Business users approve a sprint when the product works as expected, in a “Sprint review meeting”.

You need to use an effective PM tool to manage these key activities. Trello is a great choice.

Strategize Well Before You Launch a Karaoke App

You might have a great app idea, however, a project to create a Karaoke app could be complex. Additionally, future expansion into smart TV platforms will involve more complexity.
