Developing an app like Bitmoji
A project to develop an 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;
- A Project manager (PM).
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 Bitmoji-like app in multiple geographies later. You should design and develop keeping this later expansion in mind.
You should use “mobile app internationalization” techniques. These are 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.

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.
