SmileTune is an AI-driven face editing app developed by Agile Edge AI LLC. It empowers users to edit and enhance facial expressions in photographs with a focus on natural and authentic results.

The application offers a variety of features including expression transfer, 3D face rotation, and face enhancement. The expression transfer feature provides the ability to adjust facial expressions using templates across different moods.

The 3D face rotation feature allows users to adjust the pitch, yaw, and roll of their face, and the face enhancement feature aids in refining facial details while maintaining a natural look.

Moreover, the app supports various types of input such as real photos, AI-generated portraits, anime, and paintings. One key unique selling point of SmileTune is its commitment to user privacy.

All processing is done on-device, which means users' photos do not leave their device and are not uploaded to any cloud storage. It appeals to users who value a mix of creativity, control, and privacy when editing their photos.

It is worth mentioning that this app works optimally on devices with 5GB+ RAM.
