Developing a utilities app like Bitmoji

A project to develop a utilities app like Bitmoji involves the following steps:

1. Decide on the project scope

I recommend you include the following in the project scope:

  • Android app development;
  • iOS app development;
  • Chrome extension development.

2. Use the Agile methodology

Your main offering is a mobile app. Mobile apps are “Systems of Engagement” (SoEs). They require iterative development. You will likely launch a “Minimum Viable Product” (MVP) first, and then obtain market feedback.

Your further iterations depend on the feedback you receive. I recommend you use Agile methodology for such projects. Read more in “Waterfall vs Agile: which methodology is right for your project”.

3. Form a development team

Your development team for this project should have the following roles:

  • Business analysts (BAs);
  • UI/UX designers;
  • Android developers;
  • iOS developers;
  • Web developers with HTML, CSS, and JavaScript skills;
  • Testers;
  • A Project manager (PM).

You need the HTML, CSS, and JavaScript skills to develop the Chrome extension.

Consider using the tried-and-tested “Scrum” technique to manage this Agile project. In this technique, the PM is the “Scrum master”, and the PM forms small cross-functional teams called “Scrum teams”. Designers, developers, and testers work together in such teams. Read more about Scrum in “How to build a Scrum development team?”.

4. Prepare for later geographical expansion

You might launch your app targeting one geographic region only, to start with. However, you will likely launch a utilities app like Bitmoji in multiple geographies later. You should design and develop keeping this later expansion in mind.

You should use “mobile app internationalization” techniques. These are the processes/methods/guidelines that make the future launch in more geographies easier. Read “7 tips for mobile app localization” for guidance.

5. Sign-up with an MBaaS provider

You have noticed that I have not included any mobile backend developer or cloud platform architect in the team. I recommend you use a “Mobile Backend as a Service” (MBaaS) provider, and that’s the reason. Sign-up for an account with SashiDo, a popular MBaaS provider.

Using an MBaaS account helps you in expediting your project since you get the following advantages:

  • Mobile backend development from scratch takes a significant amount of time. It also requires planning and provisioning of infrastructure. MBaaS providers save that effort for you.
  • You will target various platforms and a wide range of devices. MBaaS providers handle that complexity for you.
  • An MBaaS provider will address the persistent storage for you.
  • MBaaS providers help with user management.
  • You can easily implement push notifications when you use an MBaaS.
  • MBaaS providers have impressive security capabilities, and this helps.
  • You can integrate 3rd party APIs easily when you use an MBaaS.
  • Automated scaling solutions of MBaaS providers are helpful for developers.

Read our guide “How to choose the best Mobile Backend as a Service (MBaaS)?” to understand these advantages better.

6. Get the license for an emoji library

You will let users create their personalized emojis, therefore, you need to access a comprehensive emoji library first. Sign-up with EmojiOne. This offers the following advantages:

  • EmojiOne is a comprehensive emoji library, and it has 2,827 emojis.
  • All emojis are 100% Unicode compliant.
  • There is a premium plan where you will get all SVG files for vectors and large PNG files.

  • The user engagement increases for your app with this well-constructed SDK.
  • It’s easy to add custom emojis.
  • You can implement various monetization approach.
  • The SDK is free.
  • Emojis and messages use HTML image and paragraph tags.
  • Gif support is available.
  • The SDK is hosted with AWS, and it scales well.

There is extensive documentation available.

8. Sign-up for an eCommerce API

I recommend you use an eCommerce API to handle the in-app purchases functionality. This will save time since you don’t need to code this functionality from scratch. BigCommerce offers a robust set of eCommerce APIs, and I recommend you use these. These APIs offer the following advantages:

  • A developer will find it easy to use these RESTful APIs.
  • All APIs are documented using Swagger.
  • The APIs integrate well with other software you might use to run your business, e.g., CRM software.
  • BigCommerce APIs offer key eCommerce specific native features like faceted search, etc.
  • The suite includes catalog API, login API, cart API, etc.
  • There is a wide range of learning resources like archived webinars. A programmer using these APIs benefits from these.

9. Design the right mobile navigation menu for your app

The mobile navigation menu is important for UI. Carefully analyze your requirements, and choose from the range of mobile navigation menu examples, as follows:

  • Hamburger menu;
  • Tab bar;
  • “Priority +” menu;
  • “Floating Action Button” (FAB);
  • Full-screen navigation;
  • Gesture-based navigation.

Read more about these patterns in “Mobile navigation menu examples”.

10. Choose an appropriate mobile app color scheme

Your mobile app UI should use a suitable color scheme. Choose one from trending color schemes, which are as follows:

  • Minimal color usage with focused palettes;
  • High-contrast colors;
  • Subtle colored shadows;
  • Bright colored iconography;
  • Pastel, muted colors;
  • Confine the choice of colors to white, black, and grey;
  • High-contrast, complimentary gradients;
  • Colorful illustrations.

You can learn more about these in “8 trends in mobile app color scheme”.

11. Design suitable icons for the mobile app

A great mobile app UI needs appropriate icons. Design icons using the following best practices:

  • Use restraint in your design. Keep the design simple and consistent with the overall UI design.
  • Make use of recognizable icons.
  • Keep in mind that icons should be memorable.
  • Check out the Bitmoji app, and use ideas from there. However, differentiate your icons sufficiently.
  • Use appropriate tools.
  • Design icons that work well irrespective of size and background.
  • Your icon design for Android and iOS apps should meet the respective platform guidelines.
  • Use established icon/functionality associations.
  • Mobile app icons can’t take a lot of space, therefore, limit the number of symbols in your design.

Check out our guide “How to design the perfect icon for your mobile app?” for more details.

12. Use Android Studio and Kotlin to develop the Android app

Android Studio is the popular Android “Integrated Development Environment” (IDE). I recommend you use it, along with the modern programming language Kotlin. Kotlin offers multiple advantages, as follows:

  • The concise syntax of Kotlin lets developers implement the required functionalities with less code.
  • Developers can avoid common errors like null pointer exceptions with Kotlin.
  • Android app development using Kotlin is easy since there is excellent documentation available. Check out “Get started with Kotlin on Android”.
  • Kotlin supports functional programming, therefore, developers experience higher productivity.
  • The language is fully compatible with Java. Developers can use all Java libraries and frameworks.
  • The Kotlin library is small, therefore, there’s no runtime overhead. You can code performant apps.
  • Kotlin is an open-source language, and there is a vibrant developer community-enhancing it further.

Read about these advantages in “Kotlin vs Java: which is the best choice?”. You need to integrate EmojiOne, Makemoji Android SDK, and BigCommerce APIs.

13. Use Xcode and Swift to code the iOS app

You should code the iOS app using Xcode, which is the popular IDE for iOS development. I also recommend you use Swift, the modern, popular programming language that Apple promotes. There are many advantages of using Swift, for e.g.:

  • Swift has operators for string control, class division, etc. This reduces the coding effort.
  • It’s a lightweight language, therefore, developers can create performant apps.
  • Swift has features like Generics and “type interference”. These help in reducing coding errors.
