Similarities: the way to get traffic + differentiation highlights

In recent years, the "beauty economy" has become a trend, and all kinds of consumer products related to beauty have sprung up like a spring.

App developers also began to eat this big cake, the number of apps mainly focusing on beauty, photo retouching, face changing and other functions are endless, and to quickly occupy the market, it is extremely important to find the differentiation highlights and take advantage of the traffic of the promotion platform.

Identify differentiated highlights

Face swapping app hits the contemporary people's imagination of the time machine, using this software can let you experience the wonderful process of turning from a child into an old man, bringing you back to the childhood in a second, so that the trend of "getting older" and "getting younger" swept the whole Tiktok.

It is not difficult to find that the recent fire Face swapping app has found its own differentiation highlights, to achieve the function that other face swapping apps have not achieved, so as to attract users to download.

Must-have features of a face swap app 

As you have got the idea by now that these face-changing apps have a bright future ahead. This is your time to conquer this lesser-explored territory. Your face swap app should have some basic features that are a must for this genre to achieve success. Remember, the right set of features can get a high ROI.

Face editor

Face editing is a must-have feature as it will allow the users to scan the clicked image and assist them in editing by delivering them options like crop, retake, rotate, adjust light, contrast, etc. This feature will help users select their best photos, and the application will know which part of the face needs to be modified as per the selected GIF.



This feature will act as a search tab or news feed. This section will help the users search for their favorite videos and access popular ones along with the most liked or featured videos of a day. This section will encourage the users to search and try the most used filters of the day. Your app should have this feature to deliver ease of access.

Personalized suggestions


As the app runs on AI-powered Deep faking technology, your app will learn the behavior of users as per their previous choices, and on that basis, it will suggest them some top filters. Remember, personalization is the key, everyone loves to be pampered, and your users will be no different. This feature can increase the engagement rates of your portrait ai app.

Social sharing


Sharing is the main agenda behind the popularity of apps like Reface. Everyone wants to tell the world about their excellent editing skills or every new thing they tried. Your users would want to share the edited GIF made in your app, and to do that, your app should allow sharing of content across all the social media platforms. It will serve you two purposes: your user will be happy by sharing their content, and you will get free brand recognition.

Download/delete videos


If the user made a GIF or a face swap video and changed his/her mind later, then your app should deliver them an option to delete that GIF or video. The same goes with the download feature. This feature will access the storage of the user’s device, and the user has to allow the app for the same. There are various times when users don’t like their edited click or the filters or the apparel color and want to delete it. The highest numbers of the shared contents include the downloaded, edited clicks.

Advanced search functionality


Your face-changing app should have a search button that will allow the users to browse through their favorite filters and creators. Apart from that, your app should have an advanced search option that will allow users to search for popular clips, filters, etc. This feature should allow users to filter their search results based on parameters such as language, popularity, creator, most used, etc.



Uploading is the essential part of any face portrait ai app, as after spending your time on the app while browsing, searching for the correct filter and editing your click, you will ultimately upload it. But if the users have some other filter in their mind and cannot find it on your platform, then your app should have an upload button that will allow them to upload their own video clips or GIFs. This feature will help your app add the other features or filters unavailable in your app’s library.

The development process of a face changer app


With the correct features, you can develop a successful app like Reface. Now you know about all the essential features that you need to embed in your project. The next level is the development process of these apps. Like any other business, you have to analyze the market for your competitors and learn their strategies, if possible.

This research will help you understand the working of this domain. Convene a meeting with all your members and discuss the issue of the budget with them and decide a range of money that you are willing to spend on this project. After that, move to decide the platforms on which you want your app to operate. This decision will decide your app’s success. Operating on more platforms will give your users an ease of mobility.

Technologies to consider 

While developing a face swap app, Artificial Intelligence plays an important role. Along with that revolutionary technology, Google Cloud API is a must. This is the tool that will make your app work faster in terms of operation. This API will work as the critical foundation for your portrait ai app.

To develop a face swap app, Google Cloud API is mandatory as it is a set of different classes, structures, procedures, and functions that exist in a bunch within a cloud. API is responsible for identifying the link between your device and that particular cloud that consists of various layers of information within.

To create images and GIFs with various filters on them, your app will have to use the deep generative convolutional neural networks that are a powerful group of networks. These are used for high-fidelity raw image synthesis, enhancing image compression, and augmenting data. These Understanding Generative Adversarial Networks (GANs) are known as a structure of an algorithm that uses two of the very conflicting neural networks that contest against each other to create new information.
