## What is LightU?

Transforming your phone into a professional fill light and correcting the lighting anytime and anywhere, LightU is a beauty filter and fill light software that maximizes the iPhone's photographic functions. It supplies soft, natural lighting under subpar environmental lighting conditions (backlight glare, overhead lighting, dimly lit environments etc.), while improving skin texture and highlighting your facial features to take shots to rival a pro's.

Have you ever encountered any of the following issues while taking photos?
- Backlight glare caused by light in the background that casts shadows on the faces of subjects.
- A light source above the subject that casts shadows on the eye sockets, under the nose and highlights imperfections on the face.
- Insufficient light at night, indoors, in bars, museums, and so on.
- Faces looking pale and uninteresting when filling light with the mobile device torchlight function.
- Using your mobile device screen as a light source prevents you from taking your selfie at the same time.
Perhaps the only difference between your photos and an influencer's is the use of pro fill light equipment. 

With LightU, transform your mobile device into pro fill light equipment and take care of all the above issues. Just open LightU and hold your mobile device screen at a 45-degree angle to your face to fill light naturally. No matter how bad the light is, the app will capture you at your best like a pro!
