Scanner App

A Swift-based app for saving, editing, signing, filtering, and sharing documents in several formats. As an iOS developer, my contributions included creating several UI animations and filters that can enhance images, image handling, and object detection.

ArtSync: Augment Reality Image Tracing Studio

https://artsyncapp.co
ArtSync app is my solo-developed iOS app.
It is an image tracing app that harnesses the power of augmented reality to position and layer multiple images on the artist's desired surface (be it a canvas or a wall) for an easier drawing experience with image tracing.
The app also allows its users to record high-quality normal or time-lapse videos for artists' social media needs.

The app is in the review process by Apple. An App Store link will be provided soon.
