How to Build a Photo Booth App: Architecture Tips

Think twice, build once. It is the first advice we give any entrepreneur who wants to turn the classic photo booth into a new entertainment experience.

The final user sees only the surface of the product. Under the simple act of taking a picture with one touch on a screen lies a whole complex mechanism. The app developers must follow a set of key rules that cover the issues that can appear with this kind of software.

These are our four tips on how to build a photo booth app.

1. App architecture

Scalability is a top priority when you build any product with a large user base or a plan to add features over time. There is one way to make sure a photo booth app is ready for the moment the project hits a serious size: the app architecture must be set up correctly from the very start.

The MVC pattern (Model-View-Controller) was the most popular way to separate an app's concerns for a long time among iOS apps. It is still a good choice for small projects. But for better scalability, since people always want more features later, we recommend MVVM or Clean Architecture for mobile projects. They offer better separation of concerns and better testability.

So, if we think about a photo booth app, people always want a more fun interaction and more options while they capture the moment. MVVM (Model-View-ViewModel) may be the go-to option. It uses a markup language to separate the development of the graphical user interface.

Clean Architecture is a great approach too. It keeps your app infrastructure testable and independent of frameworks, UI, database, or any external agency.

2. Performance and app speed for a smooth user experience

The queue for taking a picture will not go unnoticed at events.

For the best user experience, there should be no extra waiting time beyond the usual countdown between takes. The challenge is to optimise the whole process, from taking the pictures to editing them and safely storing and sending them to the server.

It is a matter of both app performance and good user experience.

On the technical side, time-consuming actions like uploading photos should run asynchronously, on background threads. They should not block the UI or the main thread until they finish.

Also, keep the balance between memory use and computing power in mind. Sometimes it is better to store a value in memory instead of computing it again. Other times, memory should be used wisely, only for the most important data.

3. Supporting several file formats

Trends change at a mind-blowing speed. Today, a photo booth does far more than take a picture. It has turned into a GIF or video booth. Make sure your photo booth app supports different file formats for a full experience.

Here are some file formats to support in an entertaining photo booth app:

• Photo files: .jpg or .jpeg
• Graphics Interchange Format: .gif
• Videos: .mov
• Multi-camera photo booths with bullet-time rig options for memorable shots and 3D captures: .raw

4. Test like there is no tomorrow

In the entertainment industry, product quality has a huge impact on user satisfaction. Imagine the app crashes during a public event. That is an expensive fiasco. It can cost you contracts and leave the final users let down.

Here, testing the product step by step is a life-saver, and a crucial part of the app development process. Before a photo booth app goes live, it should be tested with several quality assurance methods, such as unit testing, manual testing, and automation testing.
