AffdexMe demonstrates the use of Affectiva's Affdex Software Developer Kit (SDK), which lets developers emotion-enable their apps and digital experiences.

The app analyzes and respond to facial expressions of emotion in real time using the built-in camera on your iOS device. To use, simply start the app and you will see your own face on the screen with metrics at the top measuring expressions and emotions and the most likely emoji icon that matches your facial expression.

There are three icons on the right side of the screen that will allow you to:
- Select the desired emotions or expressions to track (any 6 can be shown in the app at one time)
- Switch between the front and rear-facing camera
- Take a snapshot and save to your photo roll.

The app’s preferences can also be used to:
- Change the processing frame rate
- Display facial points as the face is tracked.
- Display gender and glasses avatar
- Display emoji avatars
- Track multiple faces simultaneously (iPhone 6s and iPad Air 2 or newer is recommended for this feature)

Visit our developer portal at for more information on our SDK.

It’s doesn’t like black people.

This doesn’t read black faces... apparently I have a disgusted face all the time. These companies really need to have diverse research done before releasing to public. Come on it’s 2019 already, there are other faces than whites.

It actually works

This app is able to detect what emotions you’re feeling in real time! ,

Don’t bother downloading.

Immediately crashes upon opening.
Was really looking forward to trying this after listening to an interview with Affectiva’s founder; really disappointed.
