Filters That Make FaceApp ‘Apple of Everyone’s Eye’

1. Age Filter

When talking about Faceapp filters, the foremost filter that helped the app recreate its popularity is Age filter.

The filter is highly liked by users – a ripple effect of which is that #AgeChallenge and #FaceAppChallenge has entered among trending hashtags on social media. People are not solely enjoying adding the filter to their picture, but also on others faces.

3. Hairstyle Filter

5. Skin Tone Lightning Filter

Last but not least, FaceApp mobile application also provides users with an option to lighten their skin tone. 

While this is all about the prime filters it offers, let’s turn towards how exactly this application work.

Working of FaceApp – The App That Makes You Look Old

When you open this face changing application, it allows you to either click a selfie or pick a picture from your Gallery and apply a filter on it. On doing so, this app uses the power of Artificial Intelligence (AI) to detect the right spots for smile, wrinkles, and other features on your face. It then analyzes what difference will appear in those sections when applying the old age or any other filter. 

It uses trove of data and its learning power to deliver the most accurate results to the users – a simple proof of which is:- 

Working of FaceApp - The App That Makes You Look Old

This mobile application, just like Prisma app, uses server-side technologies to add filters on your photos and further, upload them on FaceApp’s server. However, it does not ask for access the complete photo gallery to apply filters. Rather, it accesses only one picture at a time.

Wondering how? 

While Faceapp has not yet revealed their actual tech stacks, the following are the tools and frameworks that our AI mobility experts believe are behind the spectacular features of it.

Tech Stack That Might Be Behind the Popularity of FaceApp

1. Swift and Java/Kotlin

When talking about frontend development, it is expected that this face changing application is relying upon Swift for its existence on iOS platform and Java or Kotlin for building its Android presence.

2. Python

Since the application is based on Artificial Intelligence, Python – one of the top programming languages – is also expected to be used for server-side development.

3. OpenGL or OpenCV

Either of these two libraries have also been considered as a part of FaceApp’s tech stack due to the fact that real-time processing is performed on pictures.

4. Apple API

Above all, this face changer application uses an API introduced in iOS 11 that make it possible for AR app developers to give their users an option to select a single photo from a system dialogue for further processing. 

Bonus Read: You can view the documentation of this API here.

With such filters and tech stack, Faceapp is getting a huge momentum in the market. But, at the same time, it is facing various contraversaries. A few of which are:-

1. People are accusing the application for asking for more than required permissions.

2. When you submit a photo on FaceApp, it is processed and stored on its server. However, there is no clarity of what happens to image after that, which act as an alarming factor in terms of privacy concern. 

3. Besides, various users have sensed that although this AI-face editor application claim to pick only one picture at a time, it secretly access the whole of your photo gallery and other folder. This again creates a concern in terms of privacy and security to sensitive user data.

Right now, none of these concerns have been proven true. Whereas, the app features are gaining limelight every passing day, which gives a clear indication that the company will live its dream of becoming the next billion-dollar company.

Rest, let’s keep a watch on what new FaceApp features and announcements are entering in the Face changing app market.
