7 Steps to Build a Face Filter App and Save Your Budget

In today’s world, the demand for face filters has skyrocketed. Whether you’re scrolling through Instagram, Snapchat, or TikTok, you’re bound to come across a face filter app ad. These apps are famous not only among the younger generation but also among people of all ages. With the increasing popularity of face filter apps, many individuals and businesses are looking for ways to build their own app and take the market by storm.

However, building a face filter app from scratch can be a daunting task. It requires a team of skilled developers, designers, and testers. Not to mention, it can also be quite expensive. But fear not, because there are several steps you can take to build a face filter app without spending a fortune.

Define your app’s purpose and idea

What kind of filters do you want to create? Will your AI face filter app be used for fun or for a specific purpose such as a makeup application or virtual try-on? Properly understanding your app’s purpose will help you determine the features and functionalities it needs. For example, if you’re in the cosmetic business, you can create a filter that shows how a customer can look after using a particular product. Start sketching your ideas and concepts, and lay the foundation of your future app and its interface. Think about the features you want to include, the colors, the textures, the shapes, and how they all come together to create a visually stunning and user-friendly app.

Pick a face filter SDK and integrate it into your app

The second step in building an AI face filter app is to choose a face filter software development kit (SDK). An SDK is a set of tools that incorporates everything you need to create an app quickly and easily. Basically, it speeds up the development process greatly, as there is no need to write the code for every single function from scratch. So, it is essential to choose an SDK that will suit both your needs and budget.

To make the torture of SDK choice less tough, we can recommend you check out Banuba’s Face Filters SDK. This is a cutting-edge software development kit that makes it possible for developers and creators to make face filter apps and custom AR filters quickly, decreasing the time-to-market. The SDK tailors to individual creativity, offering captivating video effects such as makeup, hair color, face morphing, beautification, triggers, video effects, and much more. These features allow creators to design unique, immersive, and captivating filters. Another benefit of Face Filters SDK is its high quality, on par or better than TikTok, Snapchat, or Instagram.

Now that you have your tools, it’s time to start building your filters. You can create your own filters or use pre-made ones and customize them to fit your app’s purpose. Don’t be afraid to experiment and try out new ideas. The key is to make them unique, fun, and engaging.

Build the back end

Building the back end of an application is a crucial step in developing any software project. It involves creating the infrastructure that powers the app, including the servers, databases, and storage solutions that store and manage the data. Building a solid back end is essential for ensuring that your application runs smoothly and efficiently, providing a good user experience.

To build the back end, you need to first identify the requirements of your application. What features and functionalities will it offer? What data will it collect, store, and process? Based on these requirements, you can choose the right technology stack, programming languages, and frameworks to build the back end.

Once you have selected the technology stack, the next step is to design and set up the servers, databases, and storage solutions. You may choose to host the servers on your own infrastructure or use a cloud-based service provider like Amazon Web Services or Microsoft Azure.

When designing the database architecture, you need to consider factors such as scalability, security, and performance. You may choose to use a relational database management system (RDBMS) like MySQL or PostgreSQL, or a NoSQL database like MongoDB or Cassandra, depending on your specific requirements.

After setting up the servers and databases, you need to develop the APIs and backend services that will interact with the front end of the application. These APIs provide an interface for the front end to communicate with the back end, allowing the app to access and manipulate data.

Create the app itself

After successfully setting up the back end, the next step is to create the app itself. This involves designing the app’s appearance and flow, creating a storyboard, developing the user interface, and incorporating various components to facilitate user interaction. Furthermore, you must add necessary functionalities and integrate them with the back end to provide users with a seamless experience.

Test and debug

Launch the simulator and initiate testing procedures. In case the app crashes or malfunctions, you need to diagnose the problem and troubleshoot it. Debugging can be a tedious and time-consuming process, but it’s a critical step in ensuring that your app is free from errors and ready to be deployed. You can also ask for feedback from beta testers to improve your app.

Launch your app

Once you have tested your app and made any necessary improvements, it’s time to launch it. You can launch your app on the App Store, Google Play Store, or your own website. Make sure to promote your app on social media and other channels to attract users. It’s crucial to ask for user feedback and take it into consideration when making improvements to your app. Continuous improvement of your app based on user feedback can help you attract and retain more users.

Building a face filter app can seem like a daunting task, but with the right tools and approach, it can be done efficiently and cost-effectively. It is essential to understand your app’s purpose, choose the right SDK, create engaging filters, build the back end, design the app’s interface, and thoroughly test and debug it before launching. With the increasing demand for face filter apps, creating one of them can be a profitable and rewarding venture for individuals and businesses alike.
