SelfieX is a free iPhone app developed by Vito Technology Inc. that allows users to take selfies using the superior rear camera of their iPhone. The app addresses the common problem faced by selfie enthusiasts - not being able to see if their face is properly framed when the screen is turned away. SelfieX solves this problem by providing voice directions to guide users in framing their face correctly, including instructions to move right, left, up, or down.

The app works by aiming the iPhone's rear camera at the user's face at the desired angle, and when the perfect angle is achieved, SelfieX automatically takes a photo. Users can then turn their device back to make quick edits such as cropping and adjusting brightness, contrast, and saturation before saving and sharing their selfies.

SelfieX is a convenient and user-friendly app that provides a solution to the common selfie-taking problem. With its voice-guided framing and automatic photo capturing, users can easily achieve well-framed selfies using the superior rear camera of their iPhone.
